| 摘 要： | 为了减小施工期工程场区滑坡地质灾害对施工生产和人员的威胁,以某隧道洞口滑坡地质灾害为例,根据现场实际情况,初步分析并确定了某隧道洞口滑坡地质灾害的预警判据,得出了滑坡地质灾害主要通过地表变形、抗滑桩顶水平位移、抗滑桩体横向应力以及降雨量来进行综合预警的方法,可为类似工程滑坡地质灾害的预警提供参考。

| Abstract: | Landslide may occur near the portal of a tunnel under construction. In the paper, the warning criterion for the landslide near the tunnel portal is determined according to the site conditions, and it is concluded that comprehensive early warning may be made for the landslide mainly according to the ground surface deformation, the horizontal displacement of the top of the anti slide piles, the lateral stress of the anti slide pile body and the rainfall. The paper can provide reference for the early warning of landslide of similar projects. |
