| 摘 要： | 通过某工程人工挖孔桩低应变反射波法实测结果与钻芯法检测结果对比分析,认为低应变反射波法检测结果可定性判断人工挖孔灌注桩桩端持力层岩土性状,岩体的纵波速度与岩石的完整程度、岩石风化程度等因素关系密切~(1~2]),本文利用低应变反射波法检测结果计算了人工挖孔灌注桩持力层纵波速度,利用计算的持力层纵波速度对人工挖孔桩持力层岩土性状进行了探讨。

| Abstract: | By comparison of measured results by reflection wave method with detection results by drilled core method of low strain of man power-dug hole pile of a construction, this paper concluded that reflection wave method detection result of low strain can qualitatively be used for judging characters of rock and soil in bearing layer at the end of man power-dug hole grouting pile, and longitudinal wave velocity of rock mass is closely related to intactness of rock and weathering degree of rocks1,2]. |
