分级支挡在滑坡治理中的应用

Application of Graded Support in Landslide Treatment

在山区修建公路时,由于特殊的地形和地质环境条件,加之工程活动,往往或造成老滑坡复活及新滑坡的产生,尤其是面对范围大或下滑力较大的滑坡,此时采用单一的防护处治结构,会造成造价过大或施工难度过大或难以根本的治理滑坡,此时需要采取多种防护方式,以保证滑坡体的稳定。文章以思茅至澜沧高速澜沧江引桥段K57滑坡为例,介绍分级支挡思路及滑坡处治处理措施,以期为工程提供参考。

When constructing highways in mountainous areas,due to special terrain and geological environment conditions,combined with engineering activities,old landslides may revive and new landslides may occur,especially when facing landslides with large areas or sliding forces.Using a single protective treatment structure at this time can cause high cost,construction difficulty,or difficulty in fundamentally treating landslides.Multiple protective methods need to be adopted to ensure the stability of the landslide body.The article takes the K57 landslide in the Lancang River approach section of the Simao Lancang Expressway as an example to introduce the idea of graded support and landslide treatment measures,in order to provide reference for engineering.
