摘    要:溶洞是修建隧道时经常遇到的病害,设计隧道时可以通过地勘资料尽量避开大的溶洞区域,以降低溶洞对隧道施工及后期运营的不利影响。为满足道路等级和线形的要求,以及通过大面积无法避免的溶洞地区时,修建的隧道一定需要穿越溶洞,以广乐高速中山顶隧道为依托工程,从超前地质预报、溶洞处理方案、施工监测三个方面进行探讨,通过几种技术手段的综合运用取得良好的经济和社会效益。

关 键 词:溶洞  TGP超前预报  地质雷达  双拱架  塑性区  监控量测

Abstract:The cave is a disease frequently encountered in the construction of the tunnel. When designing the tunnel, in order to reduce the adverse effects of the cave tunnel construction and post-operation, we can a- void the large cave area by using geological survey data. However, in order to meet the road grade and a- lignment requirements as well as a large area of the cave can not be avoided, the construction of tunnels through the cave is inevitable. Based on the project of the Zhongshan peak tunnel in the Guangle highway, this paper discussed three aspects--advanced geological prediction, cavern treatment program, construction monitoring,and achieved good economic and social benefits through the integrated use of several tech- niques.
Keywords:cave  TGP ahead of forecast  geological radar  dual-arching  Plastic zone  monitoring and measur-ing
