云南程海大朗河泥石流的形成机理及其防治方法

泥石流作为一种突发性、破坏性极大的山地地质灾害已在世界范围内引起了广泛的重视,但对有深部大断裂形成的山区沟谷泥石流的针对性研究很少。随着社会经济的持续快速增长,人与地的矛盾不断地加剧,人类活动不断地深入附近的山区,使得任何一次小的泥石流都可能造成很大的损失。因此,研究该类泥石流形成机理和防治对策,对防治该类地区泥石流具有很大的帮助,是保证该地区地质环境安全,促进经济快速发展的重要条件之一。通过对程海流域青草湾、大朗河、王官河、季官河地质灾害勘察,从地质条件、地形条件、降雨条件及人类活动等因素分析该沟泥石流的形成机理及其特征,从而探讨了该类地区泥石流的形成机理和防治方法。

The formation mechanism and Countermeasures of debris flow in Dalang river in Chenghai, Yunnan

As a unexpected and severely destructive mountain geological hazard,debris flow was paid much attention around the world,but just little research was conducted in mountain valley debris flow with deep faults flow.With the sustainable and rapid development of social economy,the contradiction between human being and the earth increases constantly,and human activities go deep into near the mountains continually,any one small debris flow can be very costly.Therefore,to study the formation mechanism and counterm...
