临泉镇上西坡塬上土体滑塌应急处治方案探讨

The Discussion on the Emergency Treatment Scheme of the Upper West Slope Plateau Soil Collapse in Linquan Town

以太佳高速公路临泉镇上西坡塬上土体外侧滑塌应急处治为例,从多方面分析了其产生滑塌的原因,通过传递系数法计算出了潜在的滑塌推力,为原因分析和处治方案提供了理论依据。通过采用前缘堆载、抗滑桩及地表截排水等措施有效地制止了滑塌的继续发展,保证了高速公路的正常运营和当地人民群众的生命财产安全,为今后类似的滑塌处治提供了借鉴经验。

Taking the emergency treatment of the upper west slope plateau soil lateral collapse in Linquan Town of Taijia Highway as an example, this paper analyzed the cause of collapse from many aspects. By transfer coefficient method, it also calculated the potential collapse thrust, which provided theoretical basis for cause analysis and treatment scheme. Through adopting the front-edge surcharge, anti-slide pile and surface interception and drainage, it also effectively stopped the continued development of the slide, ensured the normal operation of the expressway and the safety of the lives and property of the local people, which provided the reference experience for the similar collapse treatment in the future.
