摘要
为穿越重要建(构)筑物时控制顶管施工对周边土体扰动的影响,本文以北京某综合管廊下穿某高速公路为工程背景,通过数值模拟方法对顶管下穿高速公路进行研究,得出了顶管下穿施工引起道路路面的变形规律,并与现场监测结果进行对比分析,为类似的工程项目提供参考。
In order to control the influence of pipe jack ing construction on surrounding soil disturbance when crossing important buildings(structures),based on the engineering background of passing through expressway under the comprehensive pipe gallery,this paper studied the expressway under the pipe jacking by means of nu-merical simulation method,obtained the deformation law of road pavement caused by pipe jack ing construction,and comparing it with the on-site monitoring results,which would provide reference for similar engineering.
