摘要
对2014年9月武汉市江夏区法泗街岩溶地面塌陷所呈现的分布及时空动态等典型特征进行分析,对比该塌陷与武汉市多年来发生的岩溶地面塌陷在地貌单元、地质模式、成因机理和动力因素等方面的异同点,揭示其产生的地质背景条件和控制因素。通过研究分析认为,江夏区法泗塌陷与武汉市区岩溶地面塌陷所处的地质构造单元不属于同一构造单元,为武汉地区一新的岩溶地面塌陷易发区域,塌陷的分布特征与时空动态特征受地质构造单元、水文地质单元及地下水动力作用等因素控制。
The analysis on the distribution, spatiotemporal dynamics and other typical features are presented about the karst ground collapse of Fasi Street,Jiangxia District in Wuhan city on September 2014. The differences and similarities in landform unit, geological model, formation mechanism and dynamic factor etc. are contrast to this karst ground collapse with others happened in Wuhan, and it reveals the geological background conditions and control factors for collapse pro- duction. Through study and analysis,it is believed that the geological units of collapse at Fashi Street and the others at Wuhan city belong to different tectonic units;the former is a new region where karst ground collapse occurs easily. The distribution features and spatiotemporal dynamics features of collapse are controlled by its geological tectonic unit, hydro- geological unit, dynamic action of groundwater.
