公路隧道质量检测与控制研究——以十漫高速公路隧道为例

针对十漫高速公路隧道受两郧断裂带的影响,在隧道施工期间出现围岩大变形、坍塌、初期支护开裂及隧道涌水,且运营期间可能出现衬砌开裂、地下水下渗、偏压危害等一些质量问题,提出了相应的处理对策,并结合工程实际以及采用在现场进行锚杆拉拔力测试、超声波和地质雷达检测衬砌及混凝土质量等,提出了控制公路隧道质量的几个关键问题,建立了一个包括业主、设计、监理、施工各方共同参与的质量控制体系.

Research on Controlling the Quality of Highway Tunnels: Taking Shi-Man Highway Tunnel for Example

Due to the impact of Yunxi-Yunxian fault zone,there are some quality problems in Shi-Man highway tunnels during the construction,such as large rock deformation,collapse in the early support and inflowing water,and there may exist lining cracks,groundwater infiltration and damages because of the partial pressure in the operation period.In response to these issues,this paper proposes corresponding resolutions,puts forward some key issues for controlling the quality of highway tunnels by taking some quality in...
