摘　　要：广西属于典型的喀斯特地质,溶洞、裂隙发育充分,岩面倾斜角度大小不一,地质情况复杂。在建筑工程中采用桩基础时,目前多数采用机械冲孔成桩。但此法在施工中经常会遇到卡锤现象,处理不好会影响工程施工进度和成孔质量。找出卡锤原因并制定对策,可提高冲孔效率和保证施工质量。Guangxi behmgs t. the typical karst geoh^gy, which has the typical eharacteristies in aspects of the karst cave and crack dew-lopment fldly, different oblique angle size on the rocks, complicated geological conditions. Mechanical punching pile use.I widely at presenl when pile fotmdalion is adopted in the construction engineering. But this method often enctmntez,＇s card hammer in construction, it will affects the project constmctian schedule and the quality of the hale if we cannot deal with. Finding out the reas.ns of carol hammer and fm＇mulating countermeasures can improve the efficiency of punching pile and en- sure constrm.liml quality.
