临近建筑物的双侧壁导坑工法风险分析及控制

On analysis of construction methods for two-side pilot tunnel in adjacent buildings and their control

以沈阳拟建地铁矿山法区间侧穿建筑物为例,采用中隔壁工法和双侧壁导坑工法进行施工,利用有限元软件模拟隧道施工过程,重点分析了双侧壁导坑工法施工时隧道、建筑物的变形和位移,并进行了安全评估,结果均满足规范安全性要求。

Taking the building side penetrating the section of planned subway mine method in Shenyang as the example,the paper adopts the median septum construction method and double side wall tunnel to undertake the construction,adopts the finite element method to simulate the tunnel construction,analyzes the deformation and displacement of tunnels and buildings in the two-side pilot tunnel,undertakes the safety evaluation,and proves the result can meet the demands for the regulation.
