【摘要】 文章介绍了某高速公路偏压连拱隧道在衬砌结构发生严重破坏和隧道上方产生规模较大的山体开裂的情况下 ,所采取的病害处理措施。首先通过地震CT手段对该连拱隧道出现的工程地质病害进行探测 ;然后据此探测结果对该连拱隧道施工全过程进行动态施工模拟研究 ;最后分析导致该连拱隧道衬砌结构发生严重破坏的可能原因。结合现场病害调查结果 ,提出了相应的建议处理方案和施工过程中应注意的几个关键性问题更多还原

【Abstract】 The paper introduces the measures adopted to treat the severe defects in the lining of an unsymmetrically loaded multi-arched highway tunnel with large-scale cracks in the mountain mass above it. Firstly, seism CT method was used to detect the defects of the engineering geology of the tunnel. Secondly, according to the detected results of the seism CT, dynamic simulation of full-stage construction was performed. Finally, possible causes leading to the severe lining destruction were analyzed. According to the in-situ defect investigation results, corresponding measures and some key problems to be noticed during construction are put forward.更多还原
