摘要
随着重庆经济增长和交通建设的日益发展,隧道工程建设引起的地面塌陷灾害已经成为中梁山地区最严重的地质环境问题之一,给该地区的经济发展和人民生命财产安全造成了严重影响。以2017年高分二号卫星高空间分辨率影像数据为主要信息提取源,在建立塌陷灾害遥感解译标志的基础上,对中梁山地区的塌陷灾害进行遥感调查和野外验证,共解译岩溶塌陷点120处。研究表明,中梁山岩溶塌陷主要分布在隧道两侧的三叠系下统嘉陵江组、大冶组地层,人为因素(修建隧道)是塌陷灾害的主要诱发因素。
With the development of Chongqing's economic growth and traffic construction,the ground collapse caused by tunnel construction has become one of the most serious geological environmental problems in the Zhongliang Mountain,which has seriously a ected the economic development of the region and the safety of people's lives and property.Taking the high-resolution image data of GF-2 in 2017 as the main source of information extraction,on the basis of the remote sensing interpretation of the collapse disaster,we carried out the remote sensing investigation and eld veri cation of the collapse disaster in the Zhongliang Mountain.The result shows that the karst collapse of Zhongliang Mountain is mainly distributed in the triassic lower Triassic Jialingjiang formation and Daye formation on both sides of the tunnel,and the human factors(building tunnels)are the main inducing factors of collapse disasters.
