Stress Analysis of Asynchronous Construction of Pylon and Bottom End Rail of Hybrid Girder Cable-stayed Bridge
摘要
Abstract
A bridge is used with the diamond type concrete pylon, and its total height is 177.91 m.In the intersection position of the Middle-Pylon and the Down-Pylon is the bottom end rail.The construction method of the pylon and bottom end rail are asynchronous constructed, which is we put the middle-pylon into the second construction segment, and then go on the bottom end rail.During the peri-od, pylon will appear cantilever state, so the weak section prone to tensile stress;it is to be avoided in the bridge construction.The pur-pose of this paper is to simulate asynchronous process, to analyze the influence to the tower, and to give the corresponding construction measures.关键词
