| 摘 要： | 本文通过收集近年来北京市东城区地面塌陷实例，并通过钻孔等资料建立了该区的三维地质结构模型。利用模型分析了该地区地面塌陷事故发生的地质原因，提出了人工填土层不均匀沉降、砂质粉土层发生流砂，是塌陷发生的主要地质因素，降雨和地下管线渗漏是外在诱因。

| Abstract: | By collecting examples of ground subsidence of Dongcheng District recent years, as well as drilling and other data, it has established a 3D geological structure model of the area, and used the 3D model to analysis the causes of ground subsidence. Finally, this paper concludes that the grand subsidence is mainly caused by the uneven settlement of artiifcial ifll soil and quicksand, and the external incentives are the rainfall and underground pipeline leak. |
