盾构隧道近距离通过高层建筑物时隔离桩参数优化设计
Optimization Design of Isolation Pile Parameters in Shield Tunneling for the Control of Deformation of High-Rise Buildings
摘要
Abstract
The shield tunnel construction disturbance effects of Taiyuan Metro Line 2 Shuang‐taxi Street~Dananmen interval were studied by FLAC3D numerical simulation method .With pile length ,pile diameter and pile spacing as factors ,subsidence and tilt rate as indexes ,orthogonal test method was used to study the effect of isolation pile on tunnel which closely passes high‐rise building ,and the parameters of the isolation pile were optimized .The results show that the rea‐sonable selection of parameters is beneficial to controlling the deformation of buildings .For the building deformation ,pile spacing is the first influence factor ;the second one is the pile length and the third one is the pile diameter .From the comprehensive effects of deformation control and construction cost control ,the obtained pile spacing is 1.2 m ,pile length is 30 m ,pile diameter is 800 m m .关键词
