摘　　要：针对高沙土地区变电站内部出现塌陷和地面沉降的现象,在分析其成因的基础上,以如皋野树变电站作为典型进行了专门的调查研究。通过现场渗水试验、轻型动力触探(N 10)、静力触探以及颗粒分析等相关试验,发现变电站内部土体的物理性质相对于变电站外部的天然土体,物理力学性质更差,渗透性更大,土体中细颗粒含量更低。In view of the phenomenon of collapse and land subsidence in the substation of high sandy soil area,based on the analysis of its causes,a special investigation and study was carried out with Rugao Yeshu substation as a typical example.Through the field seepage test,light dynamic penetration test(N 10),static penetration test and particle analysis and other related tests,it is found that the physical properties of the soil inside the substation are worse than the natural soil outside the substation,with greater permeability and lower content of fine particles in the soil.
