Abstract
With the U-shaped structure set in the subgrade transition section from tunnel to elevatedbridge on Daxing Line of Beijing rail transit as the background, this paper introduces its structural designand construction technology. U-shaped structure is the retaining structure to resist earth pressures, waterpressures and buoyancy, also to prevent surface and ground water from intruding into the subgrade. Thepaper introduces the basic theory, calculation methods, design and construction of the U-shapedstructure.关键词
