鄱阳湖流域暴雨型泥石流形成机制与动力特征——以江西修水县卢庄沟泥石流为例
Formation Mechanism and Dynamic Characteristics ofRainstorm-induced Debris Flow in Poyang Lake Valley ofJiangxi Province
摘要
Abstract
The formation mechanism and dynamic characteristics of rainstorm-induced debris flow in Poyang lake valley of Jiangxi Province is researched, which was expected to provide a reference for this kind of mountain torrent disaster and safety of river basin water project.Through field investigation and laboratory test, Luzhuang debris flow of Huanglong County in Jiujiang City was selected as an example, and the development characteristics and kinetics characteristics were analyzed.The main channel length of the debris flow is about 6.25 km, the catchment area is 4.270 km2.The supply of source was comparatively abundant(about 62.46×104 km3), the longitudinal gradient is 524.1‰ and the height differences is 1160m, the topography is easy to catchment.The process of rainstorm-induced debris flow in the study area can be divided into 4 stages: debris flow-source formation;loose accumulation carry;older landslide resurrection and debris flow initiation.关键词
