Tunnel portal landslide disposal method
The invention discloses a tunnel portal landslide disposal method, which relates to the technical field of tunnel construction, and comprises the following steps: firstly, carrying out anti-slip box body foundation excavation on bedrock; carrying out anti-slide pile construction on the anti-slide box body; further, the anti-sliding box body and the open cut tunnel are constructed, and the length of the open cut tunnel is prolonged on the basis of the original design length; then, an anti-sliding retaining wall is constructed on the anti-sliding box body; and finally, backfilling concrete on the inner side of the anti-slip retaining wall in a back pressure mode, carrying out back pressure on the slope toe of the landslide body, locking the landslide body, and completing the gliding force transmission of the whole landslide body. The slip force transmission path of the slip mass is from the slip mass to the back pressure backfill concrete to the anti-slip retaining wall to the anti-slip box to the anti-slip pile to the bed rock; the tunnel landslide comprehensive disposal method is based on open cut tunnel extension, the anti-sliding box body, the anti-sliding retaining wall and back pressure backfilling, and the ecological environment is prevented from being damaged by a large-excavation and large-filling traditional landslide disposal method.
本发明公开了一种隧道洞口滑坡处置方法，涉及隧道施工技术领域，包括：首先在基岩上进行阻滑箱体基础挖掘；再进行阻滑箱体的抗滑桩施工；进而进行阻滑箱体及明洞施工，明洞长度在原设计长度的基础上进行延长；然后在阻滑箱体上进行抗滑挡墙的施工；最后在抗滑挡墙内侧反压回填混凝土，对滑坡体坡脚进行反压，对滑坡体进行锁定，完成整个滑坡体下滑力传递；所述滑坡体下滑力传递路径为：滑坡体→反压回填混凝土→抗滑挡墙→阻滑箱体→抗滑桩→基岩；本发明，是基于明洞延长+阻滑箱体+抗滑挡墙+反压回填的隧道滑坡综合处置方法，避免大挖大填传统滑坡处置方法对生态环境造成破坏。
