| 摘 要： | 年北京地面塌陷呈波动式上升趋势,威胁严重.在讨论其孕灾环境和时空分布特征的基础上,分析引起地面塌陷的因素.研究把此区地面塌陷分为采矿地面塌陷和工程地面塌陷两种类型.采矿地面塌陷主要分布于西山门头沟,致灾因子包括开采深度、矿体倾角、降雨、和大量疏排水.工程地面塌陷主要分布于城区,致灾因子包括管线渗漏与侵蚀、地下水过度开采...

| Abstract: | Ground subsidences have,increasingly,been threatening Beijing severely in recent years.Their environments｜ and temporal-spatial distribution,as well as their causes,are discussed here.Furthermore,they are classified here into two types： mining and engineering.The former is mainly distributed in the Mentougou valley of West Mountain,with mining depth,ore-body dip-angle,rainfall and drainage as the main causes,while the latter is in the urban area,with pipeline leak-erosion,groundwater overexploitation,improper construction methods and artificial vibration as the main causes. |
