摘要
岩溶塌陷是制约岩溶地区社会经济发展的主要地质环境问题之一。武汉市岩溶地质条件十分复杂,隐伏岩溶区分布范围较广,在自然和人为两方面诱发因素作用下,近年来发生了多起岩溶塌陷。本文在全面梳理武汉市已发生的岩溶塌陷基础上,从可溶岩岩溶发育程度、地下水水位与基岩面关系、第四系厚度和结构特征三个方面,概化了区内岩溶塌陷区的八类地质模式;结合塌陷产生过程和主控机理,将武汉市岩溶塌陷初步概括为九种致塌模式。
Karst collapse is one of the main geological environmental problems,and restricts social and economic development. The karst geological conditions are very complex in Wuhan City. A number of karst collapse happened in recent years due to natural and human factors. This paper analyzes and classifies the karst collapse in Wuhan City according to the development characteristics of karst collapse in Wuhan city. The geological conditions can be sorted into eight kinds taking consideration of the corrosion degree of carbonate,the relationship between groundwater level and the bedrock surface as well as different thickness and structure of the quaternary. According to the collapse mechanism and its predominant factors the karst collapse in Wuhan is preliminary summarized as nine collapse modes.
