摘　　要：在对岩溶地区工程地质条件分析基础上,针对该复杂场区选用合理的基础形式,并结合岩溶地区桩基工程的具体实例,对桩基检测方法进行选择分析,提出了采用钻芯法与声波透射法相结合,并局部采用低应变法检测,结果表明所选检测方法是可行性的,可以确保整个桩基工程的质量安全,并为相关岩溶区工程桩基检测提供可靠的参考依据.Analyzed with the engineering geological condition of karst areas, the proper foundation type was select- ed in such complex field area. And combined with a corresponding real pile foundation project, an approach of foundation piles test was presented which＇s a united application of core drilling method and crosshole sonic logging with locally low strain integrity testing. Actually the detecting results have already demonstrated the feasibility of the proposed test method, confirmed safety to the whole project, and provided a valid reference for the pile founda- tion test in karst areas.
