摘　　要：托口水电站业主营地建筑物基础主要坐落于第四系残坡积土层上,其下伏基岩为岩溶发育的碳酸盐岩类地层。文章针对了建筑场地岩溶(土洞)发育特征,分别采用弹性理论和圆弧滑动法,对营地地基稳定进行了计算的基础上,并对地基承载力及地基变形进行了分析。提出了一些相应的加固处理方案。The building foundation of the owner camp of Tuokou Hydropower Station is mainly located on the Quaternary residual slope accumulation layer, and the underlying basement rock is a carbonate strata developed by Karst. In this paper, according to the development characteristics of Karst (soil cave) in construction site, the stability of camp foundation is calculated by using elastic theory and circular sliding method, and the bearing capacity and deformation of foundation are analyzed. Some corresponding reinforcement schemes are put forward.
