摘　　要：北京西部山区地面塌陷的形成主要与该区长期以来地下采煤密切相关,煤矿开采形成的地下采空区塌落,导致地面的沉降、陷落,影响地面建筑设施的安全,甚至造成人员伤亡。房山区蒲洼乡辖区内108国道宝水段曾发生地面塌陷灾害,在勘查的基础上,论述了地面塌陷灾害的特征,分析了产生塌陷的主要原因。The ground collapse in western mountainous area of Beijing is closely related to the long-term underground coal mining. The coal mining has caused some safety problems such as underground mined- out area collapse and ground subsidence, which would affect the buildings＇ safety, and people＇s injuries and deaths etc. For example, the ground collapse disaster has taken place in Baoshui section of Road G108, Puwa Town of Fangshan District. We have surveyed the ground collapse in this area. On the basis of the survey results, the paper discusses the characteristics of ground subsidence, and analyzes its main reasons.
