| 摘 要： | 从苏锡常地区特定的地质环境背景条件出发,系统分析了地裂缝地质灾害的形成机理,即基岩起伏形态差异、第四纪沉积结构差异和水文地质条件差异是引发地裂缝灾害的内在条件,长期过量开采地下水是诱发地裂缝灾害的外在因素.通过对地裂缝灾害成因类型的系统划分,为今后进一步进行地裂缝灾害分区评价、防治规划等工作提供了先导性意见和理论基础,具有积极的现实意义.

| Abstract: | According to the basic characteristics of geological environment in Suzhou-Wuxi-Changzhou area, the mechanism of ground fissure disaster is systemically analyzed in this paper. The discrepancies in the forms of bedrock, aggradation structure of Quaternary period and hydro-geological conditions are the intrinsic factors that give rise to the ground fissure disaster, and the super-pumping groundwater is the extrinsic factor. By the systemic classification on the cause of types of ground fissure disaster, the paper has provided the directive idea and basic theory about the services for zonal evaluation and layout of prevention and cure of geological disaster in the future. All of these will have realistic significance. |
