摘　　要：岩溶地区不整合地层系统之岩土构成复杂。通过对贵州省天柱碳酸钡工程场地的勘察,选择卵(碎)石土层作地基持力层,采用浅基础方案及碎石层褥垫等地基处理措施,避让了岩溶等对地基稳定性的影响,为该地区的工程建设提供了岩土工程治理的经验。The structure of soil and rock is extremly complex in the discordance formation system in Karst area. By detailed exploration carbonated barium engineering site, sail layer with cobbles or crushed stones are selected as bearing layer. A shallow base plan and crushed stones layer are used as an effective measure in order to avoid the influence on the stability of foundation caused by karst, the project provides some experience on dealing with geotechnical engineering problems to engineering construction in the area.
