贵州某公路滑坡变形破坏模式与治理研究

以贵州某公路填方路堤滑坡工程为依托,从地形、地层、人为、自然因素等角度分析滑坡形成原因及变形破坏模式.采用传递系数法对滑坡进行稳定性计算,结合该滑坡特点拟定了三个治理方案进行比选,从安全性高、环境影响小、造价低等方面选择了矩形抗滑桩支挡方案;并做好截、排水措施,使滑坡处于稳定状态.

Study on Deformation Failure Modes and Control of a Highway Landslide in Guizhou Province

The cause of landslide formation and deformation failure mode of a road embankment in Guizhou was analyzed from the perspectives of topography, strata, man-made, natural factors, etc. The stability of the landslide was calculated using the transfer coefficient method, and three treatment plans were drawn up for comparison and selection based on the characteristics of the landslide. In terms of high safety, low environmental impact, and low cost, the rectangular anti-slide pile supporting plan was selected and interception and drainage measures were taken to keep the landslide in a stable state.
