为改善通航条件、提高航道等级,对山区河流泥石流灾害防治技术进行了研究。根据形成机理、运动规律、成灾机制、岸坡的地形地貌特点,把山区河流型泥石流分为坡面流和沟谷流;基于土质结构原理与岩土稳定理论,提出了修复植被、规范人类行为与截流排水、拦粗排细、转向导流等工程防治技术相结合的山区河流泥石流灾害的综合防治技术。结果表明,该技术能有效防治坡面泥石流或沟道泥石流对河流的破坏,确保航运畅通。
In order to improve the navigation conditions and improve the grade of waterway, the paper studies the prevention and control of debris flows in mountain rivers. Based on the formation mechanism, the movement rule, the disaster mechanism and the landform features of the slope, the mountain-type debris flow is divided into slope flow and valley flow. Based on the theory of soil structure and stability of rock and soil, the paper proposes the methods of rehabilitating vegetation and standardizing human behavior Comprehensive prevention and control technology for debris flow hazards in mountainous rivers combined with project prevention and control technologies such as intercepting drainage, interception and rowing, diversion and diversion. The results show that the technology can effectively prevent the slope debris flow or channel debris flow to the river damage, to ensure smooth shipping.
