摘要
结合重庆地区采用单护盾TBM地铁隧道施工,对单护盾TBM始发至反力架拆除进行实时应力监测,利用ANSYS13.0有限元软件对反力架建模并实施荷载下进行应力分布的数值计算;通过实测数据与理论相结合,对反力架在TBM施工过程中的功能和作用进行了评价。
Single shield TBM was used in Chongqing area,the stress monitoring was adopted. The finite element analysis software was used for stress distribution calculation. Based on monitoring data and theory,the function and effect of counter force frame in TBM construction was evaluated.
