Analysis of geological disaster-breeding environment in Yongxin County, Jiangxi Province
-
摘要: 永新县位于江西省地质灾害高易发区内,地质灾害类型主要有滑坡、崩塌、泥石流、地面塌陷等。以区内地质环境条件为背景,通过对历年来已发生的370处地质灾害的综合研究,总结了永新县地质灾害的发育规律;对区内各类地质灾害进行孕灾环境分析,研究了与地质灾害发育相关的地形地貌、工程地质岩组等孕灾因子及其影响。结果表明:区内地质灾害孕灾环境受地形地貌、工程地质岩组、斜坡结构、地质构造、降雨和人类工程活动的共同控制和影响。充分考虑区内地质灾害孕灾环境,以工程地质岩组和地形地貌为主控因素,将永新县孕灾环境划分为3个大区和19个亚区,为地质灾害精细化调查风险评价提供技术支撑,为地质灾害精准防控提供科学依据。Abstract: Yongxin County is located in the high geological disaster prone area in Jiangxi Province. The type of geological disasters are mainly classified into landslide, collapse, debris flow, ground collapse and so on. Based on the geological environment conditions in the area, through the comprehensive study of 370 geological disasters which occurred over the years, the development law of geological disasters in Yongxin County is summarized. The various geological disaster-breeding environment was analyzed, and the disaster-breeding factors such as topography and engineering geological rock groups related to the development of geological disasters and their effects were studied. The results show that the disaster-breeding environment is controlled and influenced by the topography, engineering geological rock group, slope structure, geological structure, rainfall and human engineering activities. Taking full account of the disaster-breeding environment in the area, with the engineering geological rock group and topography as the main control factors, the disaster-breeding environment of Yongxin County is divided into 3 large areas and 19 sub-areas, which provides technical support for the risk assessment of fine geological disaster investigation and scientific basis for the precise prevention and control of geological disasters.
