马路沟泥石流危险度评价及防治方案

摘要

根据地质勘察资料,论述了马路沟泥石流的成灾条件,包括地形条件,物源条件,水源条件等方面,及泥石流基本特征,包括泥石流规模,泥石流的发展趋势.通过两种不同的方法分别对马路沟泥石流的危险度进行评价并对比分析,两者得到的结论基本吻合,马路沟属中度危险的泥石流沟,必须对其进行工程防治.通过对沟谷形态,物源总量,有无排导出口等多方面考虑,决定采用稳拦停淤的防治方案,以保护下游移民新村及省道的安全.%According to geological survey data, the paper discusses the disaster factors, including terrain, solids, water source and so on, the basic characteristics, such as scale and development trend of debris flow in the Malu Gully. Respectively, by two different methods for evaluating the risk of debris flow and comparative analysis, the results obtained by the two methods are consistent with each other. Malu Gully is a moderate risk of debris flow; it must be controlled by engineering measures. Considering the valley shape, solids volume, with or without export of draining, etc. , it is decided to make a comprehensive prevention and control measure, dam construction to stop debris flow so as to ensure the security of residents, provincial road in Malu Gully.
