广西国道G210公路高路堤“古岭滑坡”稳定性分析

Stability Analysis of “Guling landslide” of High Embankment of G210 National Highway in Guangxi

公路路堤边坡的设计是保证路网工程质量安全的最关键因素,这不仅对路基本体的稳定起到控制性作用,同时对整个路面结构功能的正常发挥也具有重要作用。分析广西国道G210公路“古岭滑坡”发生滑坡的原因并提出治理措施,包括削坡、减重、反压、排水等。最后通过数值稳定性分析进行对比,成功治理了滑坡,为交通的顺畅起到重要的保障作用。

The design of highway embankment slope is the most key factor to ensure the quality and safety of road network engineering,which not only plays a controlling role in the stability of road infrastructure,but also plays an important role in the normal function of the whole pavement structure and the normal operation of the whole traffic in the region.Therefore,this paper analyzes the causes of“Guling landslide”on Guangxi national highway G210 and puts forward treatment measures,including slope cutting,weight reduction,back pressure,drainage and so on.Finally,through the comparison of numerical stability analysis,the landslide is successfully treated,which plays an important role in ensuring the smooth traffic.
