摘　　要：主要以云南省昆明市大板桥镇某工程为例,根据野外地质调查、区域地质资料、实际地质勘探资料、实际物理勘探资料等,对云南省昆明市大板桥镇某工程所在区域的岩性—构造系统进行分析。外围地质调查表明:作为地基的龙王庙组白云岩岩溶化倾向低于灰岩,岩溶化程度总体较低。地基岩溶发育程度平面分布与场地岩性分布规律总体一致,局部受到构造控制,岩溶化程度更高一些。同时,总结了研究区岩溶发育特点,得出研究区岩溶发育的主控因素应为“岩性—构造”,此外,始新世古气候也是研究区岩溶发育的重要影响因素。With some engineering programs in Kunming,Yunnan province as an example,we developed a field geological survey,including regional geological data,the actual geological exploration data,the actual physical exploration data and etc.Through some engineering programs in Dabanqiaozhen of Kunming,Yunnan province area,we made an analysis of lithologic-structural system in the peripheral geological survey in the area.The foundation of correlation group karst tend is lower than that of limestone.Dolomite karst mineralization degree is lower overall.The level distribution of karst development in the foundation is generally consistent with the lithologic distribution of the site.At the same time,this paper summarizes the characteristics of karst development in the area.It concludes that the main controlling factor of karst development in the area is lithology-structure.In addition,the Eocene palaeoclimate is also an important influencing factor of karst development in the area.
