摘要
以重庆轨道交通三号线华新街至观音桥区间隧道工程为背景,利用ANSYS有限元软件对隧道开挖时产生的影响进行了力学模拟,重点分析了地面建筑密集地段隧道双侧壁导坑法施工的稳定性,并以隧道施工安全为目标、控制沉降为基本条件,分析了开挖中产生应力、位移的原因,据此提出了安全的施工控制措施。
Taking the tunnel engineering of Huaxin street-Guanyin bridge of Chongqing rail transit No. 3 line as an example,the paper carries out mechanical simulation of tunnel excavation impact with ANSYS finite software,analyzes construction stability of double-side-drift method at crowded buildings section,takes tunnel construction safety as target and subsidence control as basic conditions,analyzes excavation stress and displacing causes,and finally puts forward construction safety controlling measures.
