山区公路边坡滑坡稳定性分析与防治研究

Stability Analysis and Prevention Study on Mountainous Area Highway Landslide

根据山区公路滑坡体地质构造、地层岩性和水文地质等条件,考虑滑坡岩体在天然状态和饱和状态2种情况下,运用极限平衡法和F lac法对滑坡体的稳定性进行计算和分析,提出以预应力锚索框架梁和压力灌浆为主、结合岸坡防护等辅助措施的治理方案,并用F lac法对滑坡稳定性进行计算与分析,验证工程治理措施的加固效果,保证滑坡体的稳定.

According to the geologic structure,formation lithology and the hydrogeology of the mountainous area highway landslide,the calculation and analysis for the stability of the landslide were performed under the consideration of two kinds of water content with slope limit equilibrium analysis and Flac technique.The main support structure of the landslide-prestressed cable anchor frame beam and the pressure grouting were put forward as well as additional engineering measures for bank slope protection.The Flac technique was applied to the analysis and validation on landslide stability after comprehensive treatment.The landslide-treatment project is able to guarantee the stability of landslide.
