The above standards shall be implemented on June 1, 1998. China National Petroleum Corporation
December 28, 1997
This standard is based on the document (96) Zhongyou Jijianzi No. 52, and is edited by the Anti-seismic Office of China National Petroleum Corporation. In the process of compiling the standard, the members of the drafting team summarized a large number of engineering practices in salt manshi areas at home and abroad, carried out systematic scientific research in saline land areas in Qinghai and Xinjiang, obtained a large number of experimental research results, and conducted relatively extensive investigations and studies. Finally, the Petroleum Engineering Construction Professional Standardization Committee reviewed and finalized it in conjunction with relevant departments.
The main contents of this standard include: general principles, terminology and symbols: basic regulations, survey, design and construction. Inspection and maintenance, etc. It takes the solubility, salt expansion and corrosion of saline soil as the main line, scientifically solves a series of technical problems, and proposes evaluation standards for salt-collapsed soil and exploration design, construction and protection measures. The implementation of this standard can make the engineering construction in saline soil areas in my country safe, reliable, technologically advanced and economically reasonable, and play an important guiding role in the construction of saline soil areas. This standard is interpreted by the Earthquake Resistance Office of China National Petroleum Corporation. The main editing unit: Earthquake Resistance Office of China National Petroleum Corporation. Participating units: Architectural Research Institute of the Ministry of Metallurgy, Qinghai Petroleum Administration Bureau: Xinjiang Petroleum Administration Bureau: Oil Pipeline High, Oil Geophysical Exploration High, North China Petroleum Exploration and Design Institute.

This specification is specially formulated to make the construction in saline soil areas advanced in technology, economically reasonable, safe and reliable.
Construction in saline soil areas must adhere to the principle of taking measures according to local conditions, focusing on prevention, combining prevention and treatment, and comprehensive management. According to the characteristics of local saline soil, the terrain, landform, climate environment and changes in soil moisture are comprehensively considered, and the design and construction are carefully carried out.
1.0.3 This specification is applicable to the survey, design, construction and maintenance management of industrial and civil buildings in areas with soluble salt content of 0.3% to 20% (crushed stone soil is not subject to this limit). For saline soil containing mainly medium-soluble salt: this specification can be referred to for implementation. 1.0.4 In addition to complying with this code, buildings in saline soil areas shall also comply with the provisions of the relevant mandatory standards currently in force in the country.
