相对于单级滑坡,多级多层滑坡由于所处环境、地质条件得加复杂,进行整治加固亦变得更加困难。本文以某大型多层多级古老滑坡工程为例,详细介绍了多层级多级滑坡滑面位置确定、分析主断面的选取、岩土体参数的反算、各级滑坡推力的计算及多层多级滑坡的治理加固,治理工后监测结果表明,本文提出的方法是可行的,可以同类工程的整治加固有宝贵的借鉴意义。
Compared with single-stage landslide, multi-stage and multi-layer landslide is more difficult due to the complicated environment due to its environment and geological conditions. Taking a large multi-level and multi-level ancient landslide project as an example, this paper introduces the multi-level and multi-level landslide slip surface determination, analyzes the selection of main section, the back calculation of rock and soil parameters, landslide thrust calculation and multi-layer Multi-level landslide governance reinforcement, monitoring post-monitoring results show that the method proposed in this paper is feasible, and can be of similar projects remediation reinforcement valuable reference.
