摘要
为综合分析北京市平原区沉降机理,首先进行数据结构设计,开发三维地质建模系统;然后采集北京市平原区三维地质数据,进行数据格式转换等处理并载入三维建模系统;最后在系统中叠加沉降趋势图、北京平原区交通路线图,对北京市平原区沉降机理进行综合分析。结果表明:动载荷等外在因素是北京平原区沉降驱动力,而北京平原区地质构造、第四系可压缩层及断层是沉降内在控制因素。
This paper establishes a 3D modeling geological system,and the data of TIN format of Beijing plain area is loaded into the 3D geological modeling system.Furthermore,the subsidence trend map and the traffic map of Beijing plain are superimposed to analyze the subsidence mechanism of plain area in Beijing.The conclusion is drawn that the external factor of dynamic load is the driving force of subsidence in Beijing plain area,while the geological structure,quaternary compression layer and fault are the internal controlling factors of subsidence in Beijing plain area.
