喀斯特塌陷区的应急变形监测分析

Analysis on Emergency Deformation Monitoring in Karst Collapse Areas

文章以福建龙岩市新罗区某突发喀斯特塌陷区域为例,研究了喀斯特塌陷区的应急变形监测方案和监测实施过程。为了满足新罗区人民政府应急指挥部掌握实时地面稳定性的需要,需要对突发喀斯特塌陷区域进行紧急变形监测,对监测区域测绘现状地形图,研究变形监测方案。方案确定根据极坐标法,进行每2个小时为一个时间段的监测工作,并实施每日2次书面材料报告的制度。技术人员经过9个日夜的监测并计算,根据日变形速率得到塌陷区已处于稳定状态的结果。文章研究内容可为相关技术人员提供参考。

Taking a sudden karst collapse area in Xinluo District,Longyan City,Fujian Province as an example,this paper studies the emergency deformation monitoring scheme and monitoring implementation process of karst collapse area.In order to meet the needs of the emergency headquarters of the people's government of Xinluo District to grasp the real-time ground stability,it is necessary to carry out emergency deformation monitoring on areas with sudden karst collapse,and to map the current topographic map of the monitoring area and study the deformation monitoring scheme.The scheme is determined based on the polar coordinate method,the monitoring work is carried out every 2 hours and the system of 2 written material reports per day is implemented.After 9 days and nights of monitoring and calculation,the technical personnel obtain the result that the collapse area is in a stable state according to the daily deformation rate.The research content of this paper can provide reference for relevant technical personnel.
