湖南韶山市坡面型泥石流的形成机理及演化过程
|
摘要
韶山市地质环境条件较复杂,崩塌、滑坡、泥石流等地质灾害易发、频发。文章基于野外地质灾害详细调查和室内研究,以"7.1"云源村泥石流为典型案例,分析了韶山市坡面型泥石流的形成机理及演化过程。研究表明:韶山市坡面型泥石流的发育与地形地貌、地质构造、地层岩性和降雨条件等密切相关,其演化过程可划分为6个阶段。通过对坡面型泥石流的研究分析,一方面可以为该地区的地质灾害预警预报监测工作提供参考,另一方面也为该地区的防灾减灾工作提供理论支持。
The geological environment conditions of shaoshan city are complex, and geological disasters such as collapse, landslide and debris flow are easy to occur and frequent. Based on the detailed investigation and indoor research of geological hazards in the field, this paper analyzes the formation mechanism and evolution process of slope debris flow in shaoshan city, taking "7.1", debris flow in yunyuan village as a typical case. The study shows that the development of slope debris flow in shaoshan city is closely related to topography, geological structure, stratigraphic lithology and rainfall conditions, and its evolution can be divided into six stages. Through the study of slope debris flow type analysis, on the one hand can work for the region's geological disaster warning forecast monitoring for reference, on the other hand also provide theoretical support for disaster prevention and mitigation work in this area.
