This specification is revised from the "General Specification for Highway Bridge and Culvert Design" (JTJ021-89) in accordance with the requirements of the Ministry of Communications of the People's Republic of China, "Notice on Issuing the 1996 Annual Highway Engineering Construction Standard, Specification, Quota, etc. Preparation and Revision Work Plan" (JTJ021-89). During the revision process, the specification revision group conducted relevant scientific research and work with Jilin Provincial Transportation Science Research Institute and Chongqing Jiaotong University, absorbed the research results and actual engineering design experience of other domestic units, drew on international advanced standards and specifications, and compared and coordinated with relevant domestic specifications. After the first draft of the specification was completed, it was widely used in various ways. The opinions of relevant units and individuals were widely solicited, and the main contents of the specification were tested and designed. After repeated revisions, the Ministry of Transport and relevant departments reviewed and finalized the revised specification. In combination with the development and requirements of my country's highway bridges in the past 10 years, this revised specification has made relatively comprehensive improvements to the original specification. The main revisions are:
1. It is clarified that highway bridge and culvert structures should be designed for the ultimate state of bearing capacity and the ultimate state of normal use, and three design conditions of permanent conditions, short-term conditions and accidental conditions of structural design are introduced; 2. The combination mode and combination coefficient of the effects of highway bridge and culvert structure design are modified, and the combination of short-term effects and long-term effects of the action are introduced, and the frequency value coefficients of various variable action short-term effect combinations and the quasi-permanent combination of long-term effects are proposed. Duration coefficient; 3. Introduced the safety level and importance coefficient of highway bridge and culvert design, and adopted different importance coefficients according to the severity of the consequences of bridge and culvert structure damage, so as to make the structure design more reasonable: 4. Carried out a special study on "Highway Bridge and Culvert Classification Standard", and appropriately adjusted the classification of highway bridges and culverts according to the research results;
5. Carried out a special study on "Flood Frequency Standard for Highway and First-class Highway Bridge and Culvert Design", analyzed and compared the relationship between the original standard and relevant domestic and foreign standards, and compared and analyzed the calculation and analysis methods of design floods. After comprehensive analysis and comparison, it is believed that the provisions of the original specification can be maintained;
6. Cancelled the original standard automobile load level and adopted the highway first-class and highway first-class and second-class standard automobile loads; Cancelled the trailer and Tracked vehicle verification load, the influence of verification load is indirectly reflected in the vehicle load; 7. The calculation method of vehicle impact coefficient, which takes span as the main influencing factor, is changed to the calculation method with structural fundamental frequency as the main influencing factor:
8. The standard value of crowd load is partially adjusted: 9. The calculation formula of wind load and various influencing coefficients are adjusted, and the basic wind speed chart and the basic wind speed and wind pressure value table of each meteorological station in the country are provided;
10. The calculation method and calculation formula of ice pressure are supplemented; 1

Appendix General Code for Design of Highway Bridges and Culverts (JIGL60-2004) Article Explanation
1 General
1.0.1 This code is formulated to unify the technical standards for design of highway bridges and culverts, implement relevant national laws and regulations and highway technical policies, and make the design of highway bridges and culverts meet the requirements of advanced technology, safety and reliability, applicability and durability, and economic rationality. 1.0.2 This code is formulated in accordance with the principles stipulated in the Standard for Structural Reliability Design of Highway Projects (GF/T50283) and the relevant provisions of the Technical Standard for Highway Projects (JTGBO1) of the Ministry of Transport. 1.0.3 This code is applicable to the structural design of newly built and rebuilt highway bridges and culverts of all levels. The alignment of highway bridges and culverts and their approaches should be coordinated with the overall layout of the route. 1.0.42
1.0.5 Highway bridges and culverts should be designed according to the function, nature and future development needs of the highway on which they are located. In addition to meeting the requirements of Article 1.0.1, they should also be designed in accordance with the principles of beauty and environmental protection, and take into account factors such as adapting to local conditions, using local materials, and facilitating construction and maintenance:
Bridges and culverts with standardized spans should adopt prefabricated structures, which are suitable for mechanized and factory-based construction. 11.0.6 The design reference period of highway bridge and culvert structures is 100 years. 1.0.7 Highway bridge and culvert structures should be designed according to the ultimate bearing capacity state and the normal use limit state. 1 Ultimate bearing capacity state: corresponds to the state where the bridge and culvert structure or its components reach the maximum bearing capacity or are deformed or displaced and are not suitable for continued bearing.
2 Normal use limit state: corresponds to the state where the bridge and culvert structure or its components reach a certain limit of normal use or durability.
When designing the above two types of limit states, the structural and durability requirements should be met at the same time! 1.0.8 Highway bridges and culverts should consider the following design conditions according to different types of actions (or loads) and their impact on bridges and culverts, and the environmental conditions in which the bridges and culverts are located, and design the corresponding limit states. 1. Persistent condition: The condition in which the bridges and culverts bear their own weight, vehicle loads, etc. for a long time after they are built. The bridges and culverts under this condition should be designed for the ultimate state of bearing capacity and the limit state of normal use. 2. Transient condition: The condition in which the bridges and culverts bear temporary actions during the construction process: The bridges and culverts under this condition should be designed for the ultimate state of bearing capacity, and the limit state of normal use should be designed only when necessary: 3. Accidental condition: The condition that may occur accidentally during the use of the bridges and culverts. The bridges and culverts under this condition should be designed for the ultimate state of bearing capacity. Highway Bridge and Culvert Design Code (JTGLX60-20D4)
1.0.9 When designing according to the ultimate state of bearing capacity under the permanent condition, the design safety level of the highway bridge and culvert structure should be divided into three design levels according to the severity of the consequences of possible structural damage, and should not be lower than the provisions of Table 1.0.9. Table 1.0.9 Design safety level of highway bridge and culvert structure Design safety level
Bridge and culvert structure
Extra-large bridge, important bridge
Large bridge, medium bridge, important small bridge
Small bridge, culvert
Note: The extra-large, large and medium bridges listed in this table are determined according to the single span in Table 1.0.11 of this specification. For multi-span bridges with unequal spans, the largest span shall prevail; the large and small bridges marked with "important" in this table refer to bridges and culverts on expressways and first-class highways, national defense highways and busy roads near cities. For highway bridge and culvert structures with special requirements, their design safety level can be determined according to specific conditions. The safety level of the same bridge and culvert structure components should be the same as that of the overall structure. Partial adjustments can be made when there are special requirements, but the difference after adjustment shall not exceed one level.
Special bridges should be designed for landscape; bridges over expressways and first-class highways should be coordinated with the natural environment and landscape.
Extra-large, large, medium and small bridges and culverts are classified according to the single span or the total length of multiple spans as shown in Table 1.0.11.0.11*
