【摘要】 随着建筑业的迅速发展,采用桩基处理的工程越来越多,而施工及土层等复杂因素导致桩身质量问题普遍存在,因此检测桩基质量问题显得十分重要。运用低应变无损检测方法进行检测,在现场原始资料准确无误前提下,可以检测桩身质量问题。根据在沈阳施工中见到的不同桩身质量问题,结合时域及频域计算分析,总结出完好桩、轻微缺陷桩、明显缺陷桩三种类型桩的典型曲线反应特征,借此曲线类型可做检测新区时参考。更多还原

【Abstract】 Application on the detection method of low strain and no damage,under the premises which there are correct informa-tions of worksite,the quality problems of pile body may be detected.Based on the different quality problems of pile body discov-erred in construction of Shenyang city,combine with counting and analyses of time-domain and frequency-domain,and sum up three types of pile and its reaction features of typical curve(intact pile,slightly damage pile and seriously damage pile),so that types of curve may be referenced in the detection of new areas.更多还原
