摘　　要：滩地埋管是南水北调穿黄河工程主要建筑物,位于黄河南岸子路堤至解山之间的黄河滩地下,全长3 943 m,该埋管为有压埋管,水文地质条件复杂,采用内圆外城门洞型,结构尺寸较大,直径达到7.5 m,结构安全要求高,设计采用三维有限元计算方法完成大型复杂埋管的结构分析。The pipe works buried in the Yellow River bottomland are the main structrure of the South-to-North Water Diversion East line Project which pass across the Yellow River. The works are located on the bottomland between the Zilu Earthbank on the Yellow River＇s South band and Xieshan. The total length of the pipe line is 3 943 m. The buried pipe is pressure pipe and the hydrogeological corLditions are complex. Its structure size is more big, and it has the cross profile with external inversive U-shaped outline and internal circle outline. The internal diameter is 7.5 m.Because the demand of the structure safety degree is higher, so the three-dimensional finite element method was used to finish the structure analysis for the large-scale complex buried pipe project.
