双永高速公路梨子岭隧道进口滑坡是一个较典型的滑坡与构筑物相互影响的工程案例。该滑坡坡顶高压铁塔的基础荷载重量和隧道仰坡掘进开挖及掘进爆破振动也是滑坡变形破坏产生的重要原因;滑坡的变形破坏,也导致滑坡坡顶高压铁塔基础的失稳,在滑坡坡脚的隧道衬砌中亦产生多道斜向剪切裂缝;最终形成较为复杂的工程灾害系统。在滑坡工程地质分析的基础上,采用反分析定量计算手段,评估三者的相互作用机制,并确定滑坡变形的力学机制及设计计算参数,确定采用坡体后部卸载和坡体中部锚固相结合的综合方案成功治理滑坡,可为类似工程所参考。
Landslide of the Peizhiling Tunnel of Shuangyong Expressway is a typical case of an interaction between landslides and structures. The basic load weight of the high-pressure tower at the top of the slope and the tunnel excavation and excavation blasting vibration are also the important reasons for the deformation and failure of the landslide. The deformation and failure of the landslide also cause the instability of the foundation of the landslide and the high- Multi-channel diagonal shearing cracks also occur in the tunnel lining of the foot, which eventually leads to a more complex engineering disaster system. On the basis of landslide engineering geology analysis, the counter-analysis quantitative calculation method is used to evaluate the interaction mechanism and to determine the mechanics mechanism and design calculation parameters of landslide deformation. It is determined that the combination of unloading at the back of slope and the anchorage in the middle slope Comprehensive management of landslides can be managed by similar projects.
