摘　　要：我国西南地区分布着大量喀斯特地貌,地下水与地表水不断对地下岩石溶蚀与沉淀,溶洞或溶槽的产生给建筑施工的地基处理带来较大困难。文中以西南地区某住宅项目地基处理为例,通过阐述人工挖孔桩基法的施工要点及对重难点进行分析,研究出了一种安全可靠、易于实施的岩溶地基处理方法,为岩溶地区地基处理施工提供指导,为今后同类工程施工提供样例、素材。At present, a large number of karst landforms are distributed in Southwest China. Underground water and surface water continuously dissolve and precipitate underground rocks. The generation of karst caves and grooves brings great difficulties to the foundation treatment of construction. Taking the foundation treatment of a residential project in Southwest China as an example, this paper studies a safe, reliable and easy to implement karst foundation treatment method by expounding the construction key points of manual hole digging pile foundation method and analyzing the key and difficult points, so as to provide guidance for the foundation treatment construction in Karst Areas and samples and materials for the construction of similar projects in the future.
