洞桩法车站小净距下穿运营线路施工力学分析OA
Mechanical Analysis of the Construction of Small Clear Distance Undercrossing the Operating Line of the Station by Hole Pile Method
基于某近接下穿运营线路区间新建洞桩法车站工程,采用数值分析软件对施工过程进行模拟分析,研究运营线路区间变形规律、最大及最小主应力变化趋势和发生位置;现场施工监测的发展趋势、发生位置均与模拟结果拟合度较高,且现场监测值均满足规范要求.
Based on the newly built hole pile method station project which is close to a line section of the underpass,the numerical analysis software is used to simulate the construction process,the deformation law of the operating line section,the variation trend of maximun and minimun principle stress and the occurrence locaton are studied.The development trend of the field construction monitoring,and the occurrence location and the simulation result are highly simulated.The filed monitoring values all meet the requirements of the specification.
