摘要
评估区位于河西走廊西段北部山前冲洪积平原,以砂砾石戈壁为主,风蚀沙埋、洪水冲蚀地质灾害发育。文章对地质灾害现状进行了评估,对工程建设可能引发的地质灾害进行预测,并提出了相应的防治措施。工程施工中应尽量减少扰动面积、及时回填,采取增加防尘网、洒水降尘等措施,防治风蚀沙埋地质灾害;在洪水沟修建导洪渠或挡水墙,截引、导排山区洪水,避免冲蚀建筑物,防治发生地质灾害。
The evaluation area is located in the piedmont alluvial plain in the northern part of the western section of the Hexi Corridor.It is mainly composed of sand and gravel Gobi,and the geological disasters of wind erosion,sand burial,and flood erosion are developed.This paper evaluates the current situation of geological disasters,predicts the geological disasters that may be caused by engineering construction,and puts forward corresponding prevention measures.In the construction of the project,the disturbance area should be reduced as much as possible,the backfill should be done in time,and the measures such as increasing the dustproof net,sprinkling water to reduce dust should be taken to prevent the geological disasters of wind erosion and sand burial;flood diversion canals or water-retaining walls should be constructed in flood ditches to intercept and guide floods in mountainous areas,avoid erosion of buildings,and prevent geological disasters.
