摘　　要：伴随广东地区水利管线工程的日益增多,设计工作中需要垂直支护的线路占比不断提高。基坑稳定验算中抗隆起稳定不满足的现象频繁发生,因水利行业目前尚无专项基坑支护设计规范,工作中多参照住建部规范执行。该文对住建部规范及其他较发达的沿海地区规范计算公式对比分析,尤其是抗滑力矩的逐项计算,结合实际设计经验,总结适用于广东地区的抗隆起稳定安全计算模式,可为同类设计优化成果经济性提供参考。With the increasing number of water conservancy pipeline projects in Guangdong,the proportion of lines that require vertical support in the design work continues to increase.The phenomenon that the anti-heave stability is not satisfied frequently occurs in the foundation pit stability check.Because there is currently no special foundation pit support design specification in the water conservancy projects,the work is often carried out with reference to the regulations of the Ministry of Housing and Urban-Rural Development.This paper compares and analyzes the calculation formulas of the regulations of the Ministry of Housing and Urban-Rural Development and other relatively developed coastal areas,especially the term by term calculation of the anti-sliding moment.Combined with the actual design experience,it summarizes the anti-uplift stability and safety calculation mode suitable for the Guangdong area,which will be used for similar designs in the future.Provide a reference for optimizing the economics of results.
