摘　　要：讨论了声波透射法检测大直径灌注基桩的分辨率问题。并以工程实例,说明声波透射法在检测大直径灌注基桩工作过程中应注意的问题,以避免给检测工作带来不必要的损失,防止对检测大直径灌注基桩质量的错判和误判。his paper discusses the resolution of the crosshole sonic logging and with the real cases in engineering,also illustrates some notable problems in the testing of the large diameter cast-in-peace pile,or else the mistake testing results will have been done and the needless lost will have been happened.

关 键 词：声波透射法的分辨率 大直径灌注桩 水平同步法 塑料管 桩底沉渣
