摘要
对十堰市某滑坡及其影响范围进行调查,查清滑坡变形特征和危害情况,采用定量评价方法,开展稳定性、危险性、承灾体易损性分析评价,在此基础上,进行滑坡风险分析评价,计算得到该滑坡最大财产损失为61.292万元/年,最大人口风险为1.599人/年,风险等级为极高风险,建议采取加强监测、搬迁避让或适当工程治理等方法进行风险管控,以达到防灾减灾的目的。对今后开展单体滑坡风险分析评价有一定的借鉴意义。
A landslide in Shiyan city and its influence area were investigated to find out the deformation characteristics and hazards of the landslide.The stability,danger and vulnerability of disaster-bearing bodies were analyzed and evaluated by quantitative evaluation method.On this basis,the landslide risk was analyzed and evaluated.It is calculated that the maximum property loss of the landslide is 612920 yuan/year,the maximum population risk is 1.599 people/year,and the risk level is extremely high.It is suggested to strengthen the monitoring,relocation and avoidance or appropriate engineering management methods for risk control,so as to achieve the purpose of disaster prevention and reduction.It has certain reference significance to carry out risk analysis and evaluation of monomer landslide in the future.
