跨线桥对相邻倒虹吸结构影响的三维计算分析
Three-Dimensional Calculation and Analysis of the Overpass Bridge Impact on Adjacent Inverted Siphon Structure
摘要
Abstract
Inverted siphon structure in the South-to-North Water Transfer Project is one of the important water conveyance structures. It inevitably goes across the ground structures,such as bridges. In order to study the impact on inverted siphon by the adjacent structure of overpass bridge,the inverted siphon structure-soil-overpass bridge was established based on ADINA finite element analysis software. Through the calculation and analy-sis,we find out that the influence of live load on the bridge can be neglected,without considering earthquake effect,the overpass bridge has less influence on the inverted siphon structure of displacement and deformation,but the tensile stress effect is remarkable,considering the earthquake effect,the influence of deformation and stress is both worth watching,especially the torsion deformation.关键词
