摘要
通过对软岩隧道施工期间多种病害开展技术研究,提出了在大断面软岩隧道施工中采取"三台阶法"分部施作双层初期支护的技术措施,在保证安全和质量的基础上,显著加快了施工进度,并有效地降低了施工成本,控制了隧道沉降和收敛变形,取得了良好的经济效益和社会效益。
According to the research on the various diseases during the construction,this paper put forward ＂three steps method＂segment construction technical measures in large section soft rock tunnel construction. This technology can ensure the safety and quality,and also significantly speed up the construction progress, effectively reduce the construction cost, control subsidence and convergence deformation,and achieved good economic and social benefits.
