某乡集镇岩溶塌陷勘查与治理措施

Exploration and Control Measures of Karst Subsidence in A Town

贵州省处于东亚岩溶区中心,具有岩溶最复杂、类型最齐全、分布面积最大的特点,岩溶塌陷是贵州的主要地质灾害之一。为保障岩溶塌陷区域内人民群众生命财产安全,应对该地区的岩溶塌陷进行勘查并进行治理。以贵州省某岩溶塌陷地质灾害勘查及治理工程为依据,笔者从地形地貌、地层岩性、地质构造、地下水动态变化等方面对岩溶塌陷的影响因素进行了勘查与分析,认为岩溶塌陷与上述因素密切相关,采用覆盖、回填、跨越治理等措施取得了较好的治理效果。基于此,该文根据该乡集镇本身的地质情况对其岩溶塌陷勘查与治理措施进行研究,旨在为日后防灾、减灾、避灾提供借鉴。

Guizhou province is located in the center of East Asian Karst region featuring with the most complex,diverse and widely spreading karst.Karst collapse is one of the main geological disasters in Guizhou.In order to ensure the people’s life and property,karst collapse in this area should be explored and treated.In a project of karst collapse survey and control in Guizhou,the collapse factors such as landform,stratum lithology,geological structure and groundwater dynamics are explored and analyzed to show that the karst collapse is closely related to the above factors,and the measures of coverage,backfill and crossing management are effective.Based on this,the paper studies the karst collapse exploration and control measures according to the geological conditions of Xinjian Town,Fenggang County,in order to provide reference for disaster prevention,mitigation and avoidance in the future.
