［摘要］ 复杂隐伏岩溶地区地基处理是工程建设中普遍存在的难题，基础形式的选择及处理方式需考虑建筑特点、结构安全、周围环境、施工技术条件及经济性。以坐落在复杂隐伏岩溶场地上的安龙电厂主厂房为例，在充分收集和研究相关地质资料的基础上，结合现场实际施工情况，采用跨越法、桩基法、填充法以及综合处理法等技术措施，对主厂房区域不同类型的建（构）筑物进行了地基处理与基础设计。结果表明，所采用的技术措施安全有效，且节省了施工工期，是针对该复杂隐伏岩溶场地较优的基础设计方案。最后，提出了复杂隐伏岩溶地区工程建设地基处理及基础设计的一些建议，可为类似工程建设和相关设计人员提供参考。

Abstract: Foundation treatment in complex concealed karst areas is a common problem in engineering construction. The selection and treatment of foundation form should take into account architectural characteristics, structural safety, surrounding environment, construction technical conditions and economy. Taking the main building of Anlong power plant located on the complex concealed karst site as an example, based on sufficient collection and research of relevant geological data, combined with the actual construction situation on site, technical measures such as crossing method, pile foundation method, filling method and comprehensive treatment method were used to carry out foundation treatment and foundation design for the different types of buildings (structures) in the main building area. The results show that the technical measures adopted are safe and effective, and can save the construction period, which are the better foundation design scheme in complex concealed karst site. Finally, some suggestions on foundation treatment and foundation design of engineering construction in complex concealed karst area were put forward, which provides reference for similar engineering construction and relevant designers. 

Keywords:complex concealed karst site； main building of power plant； foundation treatment； foundation design
