摘要
通过系统分析研究区地面塌陷的分布特征、形成的内在因素和诱发控制因素,认为该区地面塌陷主要是由于构造破碎带导水后引起,其形成过程大致分为缓发期、潜伏期、爆发期,是潜蚀作用、水化作用以及重力负荷三个力学效应综合作用的结果。
Through systematic analysis on the distribution characteristics,intrinsic factors and induced control factors of the ground collapse in the study area,it is believed that the ground collapse in this area is mainly caused by the water conduction of the structural fracture zone.The collapse formation process could be roughly divided into the slow-release period,the incubation period and the outbreak period.It is the result of the combined effects of three effects:groundwater erosion,chemolysis and gravity load.
