摘要
为评估贵州省金织县地质灾害易发性,探究各个影响因子对地质灾害易发性的影响以及为当地提出合理的地质灾害防治规律。本文选取地势地貌、岩体性质、岩体结构、地质构造、降水作用、人为工程活动、滑坡和崩塌的历史发生频率等七个影响因子,应用GIS技术和不同权重推断各区域地质灾害易发性高低,同时也将计算结果和评估结果与往期地质灾害发生情况相比对,以验证本次评估结果的可靠性。查明区域内地质灾害隐患发育特征、分布规律、危害对象以及形成的地质环境条件,分析其影响因素及成因机理。
In order to evaluate the susceptibility of geological disasters in Jinzhi County,Guizhou Province,the influence of various influencing factors on the susceptibility of geological disasters was explored,and a reasonable law of geological disaster prevention and control was proposed.In this paper,seven influencing factors were selected,including topography,rock mass properties,rock mass structure,geological structure,precipitation,man-made engineering activities,and historical frequency of landslides and collapses,and GIS technology and different weights were used to infer the susceptibility of geological disasters in each region.The development characteristics,distribution rules,hazard objects and geological environment conditions of geological hazards in the region were identified,and the influencing factors and causal mechanisms were analyzed.
