摘要
本文以哈尔滨保健路隧道工程为背景,采用有限元软件,根据工程实际条件,建立二维模型对隧道开挖步序进行有限元模拟分析,比较了采用不同的施工工序对隧道结构的影响。同时,根据施工中反馈的监测数据,对其进行整合和态势分析,得到了软土地层浅埋暗挖双连拱隧道在施工开挖中的地表沉降、拱顶沉降等实际数据,进一步获取了围岩稳定性、支护效果的信息和经验。
Taken Harbin Baojian Road Tunnel as background,2-dimension FEM simulation is made to tunnel excavation sequence combined with actual engineering situation. The effects on tunnel structure from different construction sequences are compared. Then,the FEM simulation is adjusted according to the monitoring data of site construction,from which the information of ground settlement ,crown settlement ,surrounding rocks’stabilization and support effects in excavation construction is obtained.
