乌什县崩塌地质灾害发育特征与影响因素研究

Study on the Development Characteristics and Influencing Factors of Geological Disaster of Collapse in Wushi County

区内由于兴建道路削坡、降雨、地震或冰雪融化等因素,导致崩塌地质灾害的发生,造成人员伤亡和经济财产损失。经调查分析,乌什县崩塌灾害多发育在坚硬-较坚硬的层状碳酸盐岩地层上,处于45°~88°之间的陡崖及陡坡区域。在地震、降水、植被覆盖率降低等自然环境条件影响下,加快了崩塌地质灾害的发生。其中,人类工程活动的不合理开发、建设是诱发崩塌地质灾害发生的重要影响因素之一。通过对乌什县崩塌地质灾害发育特征和影响因素的研究,可为当地防灾减灾、崩塌地质灾害防治提供科学依据。

In the area,due to the construction of road slope cutting,rainfall,earthquake or ice and snow melting and other factors,lead to the occurrence of geological disasters of collapse,resulting in casualties and economic property losses.Through investigation and analysis of the development characteristics and inducing factors of the collapse disas-ter in Wushi County,the collapse is mostly developed in the hard to hard layered carbonate strata,in the 45°~88°steep cliff and steep slope area,under the influence of natural environmental conditions such as earthquake,precipitation,vegetation coverage reduction,accelerated the occurrence of the collapse geological disaster.The unreasonable development and construction of human engineering activities is one of the important factors that induce the geological disaster of collapse.The research on the development characteristics and influencing factors of geological disaster in Wushi County can provide scientific basis for disaster prevention and reduction and prevention of geological disaster.
