摘　　要：在水网和沙漠地段敷设大口径长输管道,会遇到大型工程机械无法进场、管沟不易成型等困难,给管沟开挖和管道整体下沟带来很大挑战。采用双侧沉管施工方法,可解决这一难题。文章在对此工法中的管道承载问题进行力学分析的基础上,结合工程实例介绍了采用此工法进行施工的要点和注意事项,为水网和沙漠地段的管道建设提供有益的经验。Large-diameter long-distance pipeline constructions in water network or desert areas cause some great troubles, such as site entering difficulty of heavy construction machinery and trench forming difficulty, which bring great challenge to trenching and integral pipeline descending into trench. The construction method of pipeline sinking by both sides excavation can be applied to solve these problems. Based on the mechanical analysis of bearing capacity of pipeline laid by this construction method and combined with engineering examples, this article introduces key points for attention in the pipeline construction. It provides useful experience for pipeline constructions in water network or desert areas.
