多源泥石流的主要特征及整治方案

泥石流作为一种山区典型地质灾害，具有破坏能力强、预警预报困难、防治难度大的特征特点，同时具有不可重复作用因素导致其规律性不强，相关研究多以分类相应开展类比法调查研究分析为主。相对常规泥石流物源、水源分布作用相对较为固定的特征，针对当前国内相关水源、泥源、石源客观分离的多源泥石流研究较少的现状，以某铁路病害工点为例，利用无人机、机载激光雷达和现场调查等方法对多源泥石流开展成因分析、整治方案论述及治理、预警预报思路探究，为开展多源泥石流相关勘测调查、方案治理、预警维护提供支持。

Main Characteristics and Treatment Scheme of the Multi-source Debris Flow

As a typical geological disaster in mountainous areas, debris flow has the characteristics of strong destruction ability, difficulty in early warning and prediction, and great difficulty in prevention and control. At the same time, its regularity is not strong due to its non-repeatable factors, which leads to the classification and corresponding analogy investigation and analysis in most relevant studies. Compared with the characteristics of conventional debris flow's relatively fixed material source and water source distribution, in view of the current situation that there are few studies on multi-source debris flow objectively separated from relevant water source, mud source and stone source in China, taking the debris flow in a diseased site of the railway as an example, Methods such as UAV, airborne laser and field investigation are used to analyze the causes of multi-source debris flow, discuss the remediation scheme and explore the scheme management and early warning and forecast ideas, so as to provide support for the investigation, control plan and early warning and maintenance of multi-source debris flow.
