在现场调研及隧道监控量测的基础上,研究了十房高速公路通省隧道施工中出现的大变形问题,通过分析该隧道大变形破坏的特点,从围岩岩性条件、工程结构受力和施工因素等方面对该隧道的大变形机制进行了研究,结果表明通省隧道发生大变形的主导因素是隧道所处的地质环境和软弱围岩,而前期施工措施不当是产生大变形的诱因。结合研究成果提出针对大变形段的治理措施,监控量测结果表明该治理措施取得较好的效果。
On the basis of on-the-spot investigation and tunnel monitoring measurement, this paper studies the large deformation problems in the tunnel construction of the ten-room highway through the analysis of the characteristics of the large deformation and failure of the tunnel, from the rock lithology conditions, And construction factors of the tunnel deformation mechanism was studied, the results show that the main tunnel deformation occurred in the tunnel is the main factor in the geological environment and weak surrounding rock, and the improper construction of the early incentives are large deformation . Combined with the research results, the control measures for the large deformation section are put forward. The monitoring and measurement results show that the control measures have achieved good results.
