摘要:
对桩身极浅部缺陷判断和灌注桩缺陷判断的低应变测试热点和难点,结合深厚淤泥的地区特点和施工状况,采用低应变法、钻芯法和开挖验证,对大量的实测曲线和详实资料分析研究,得出:频率匹配好坏决定了低应变测试效果的好坏,以及对于超长桩和大直径灌注桩采用低应变法检测意义不大等结论
Abstract:
In view of the hot spot and difficult point about the estimate of the superficial part defect and bored concrete pile defect, and combined with the regional characteristics of deep mud and construction conditions, this article used the low strain method and drilling core method and the excavation on researching a large number of measured curve and detailed data analysis, The conclusion arrived at states that the frequency matching, determines the low strain test result. Large diameter and super-long pile piles with low strain gauge makes little sense to test results, etc. It also introduced some of our own experience
