摘要
重庆市的地面沉降问题引起了政府部门的高度重视,利用InSAR技术进行重庆市的地面沉降监测已经取得了一定的进展。本研究以重庆市的歌乐山镇为研究区,在2017—2018年歌乐山镇沉降监测成果的基础上,提出了综合考虑地面沉降可能演变为地质灾害的概率(沉降危险性)以及沉降可能会对社会经济造成的损失(沉降易损性)的地面沉降风险性评价模型,完成歌乐山镇风险性评价,为歌乐山镇的沉降防治以及减灾措施提供科学依据以及意见建议。
The land subsidence problem in Chongqing has attracted the attention of the government departments,the use of InSAR Technology for land subsidence monitoring in Chongqing has made some progress.In this study,Geleshan Town in Chongqing is taken as the research area.On the basis of the settlement monitoring results of Geleshan Town in 2017-2018,a risk assessment model of land settlement is proposed,which comprehensively considers the probability that land settlement may evolve into geological disaster(settlement risk)and the loss(settlement vulnerability)that settlement may cause to social economy,so as to complete the risk assessment of Geleshan Town for providing scientific basis and suggestions for the settlement prevention and mitigation measures of Geleshan Town.
