摘　　要：以北京轨道交通大兴线工程路基过渡段设置的U形结构为背景,介绍U形结构设计施工技术。U形结构是承受土压力、水压力、水浮力并阻止地表水或地下水浸入至路基的支挡结构物,对U形结构进行分析并介绍计算基本理论及设计施工方法等。With the U-shaped structure set in the subgrade transition section from tunnel to elevated bridge on Daxing Line of Beijing rail transit as the background,this paper introduces its structural design and construction technology.U-shaped structure is the retaining structure to resist earth pressures,water pressures and buoyancy,also to prevent surface and ground water from intruding into the subgrade.The paper introduces the basic theory,calculation methods,design and construction of the U-shaped structure.
