地面沉降作为地质灾害的一种,由于自身特点和发生区域水文地质的特异性,造成不同地区的差异性.文章对常州区域地面沉降进行研究,在永文地质和沉降史的分析基础上,通过一些监测数据,分析了该区域的土层压缩情况,并采用origin软件对清凉小学基岩标监测数据进行曲线拟合处理.分析得出,常州区域地面沉降整体得到有效控制,沉降趋于稳定,且中心城区有回弹的迹象,但周边乡镇——戚墅堰、马杭等有沉降加剧的趋势,建议对于地下水开采及地面沉降防治统筹规划,打破区域界限,进行联防.%Land subsidence as one of geological disasters, due to the characteristics and specificity of its own and the hydrogeology in outbreak regions, results in the differences of subsidence in different regions. The land subsidence in Changzhou was studied. Based on the analysis of the hydrogeology and subsidence history of Changzhou, through the monitored data, this study analyzed the compression of soil-layers in this region, and curve fitted monitored data of bedrock mark in Qingliang school by the software of origin. Through analysis, the study concluded that the land subsidence of overall region in Changzhou was effectively controlled and stabilized, and that the signs of rebound are shown, but the surrounding areas, such as Qishuyan and Mahang, has a trend to be exacerbated. It is suggested that the exploitation of groundwa-ter and the control of land subsidence should be overall planned to break regional control.
