"Embankment Engineering Construction Specifications" was included in the Ministry of Water Resources' water conservancy and hydropower technical standards revision plan in the early 1990s, and it was clearly stated that the Ministry of Water Resources' Zhunhe Water Conservancy Commission was the main editor to organize the compilation. In order to meet the urgent need for a large number of new and expanded embankment projects at that time, the Ministry of Water Resources' Science and Technology Education Department issued the "Notice on the Preparation of the Industry Standard "Embankment Engineering Technical Specifications" in the document No. Science and Education Standard [1992127], which clearly stated that the Yellow River Water Conservancy Commission and Zhunhe Water Conservancy Commission of the Ministry of Water Resources were the main editors, and the content of the specification was tentatively set as the design and construction of rolled earth embankment projects. On April 10, 1993, the Ministry of Water Resources issued SL51-93 "Embankment Engineering Technical Specifications" as an industry standard in the document No. Shuijian [1993] 207, and it was implemented on July 1 of the same year.
From April 22 to 23, 1995, the Construction Department of the Ministry of Water Resources hosted a review meeting for the compilation of the "Technical Standards for Construction of Embankments", and issued the "Notice on Organizing the Compilation of the "Technical Standards for Construction of Embankments"" in the Ministry of Water Resources Construction Technology [1995] No. 15 document. The standard compilation team conducted extensive and in-depth investigations and studies on the basis of the work done, and carefully summarized the experience of construction technologies such as rolled earth embankments, dredgers and silt release embankments, stone (wall) embankments, and concrete walls (embankments) since the founding of the People's Republic of China, especially in recent years; retrieved and translated some foreign embankment construction materials, and conducted special research on some issues in embankment construction. From September 23 to 25, 1998, the Construction and Management Department of the Ministry of Water Resources hosted a review meeting for the "Embankment Construction Standards" (draft for review) in Bengbu City, Anhui Province. The main technical contents of the approved "Embankment Construction Specifications" include: general principles, construction preparation, flood control and diversion, embankment materials, embankment foundation construction, embankment filling and masonry, protection project construction, management facility construction, reinforcement and expansion, quality control and project acceptance, a total of eleven chapters.
