摘要
针对桩基检测中的桩端性状检测,对比分析检测中应用较多、较广的几种检测技术和手段。深入了解每种检测方法的优劣,低应变方法方便快捷、成本低,但易误判;钻芯-孔内成像法直观、定量,但成本较高。故应根据不同的检测情况,选择相应的检测技术手段,以满足相应的检测需求。
Regarding to the testing of pile tip properties ,some widely applied testing techiniques and methods were com-pared and analysed here .The advantages and disadvantages of every method were studied deeply .Low strain method is simple and cost less ,but it’s prone to erroneous judgements ;whereas borehole imaging method is intuitionistic and quan-titative ,but demands high cost .So proper testing method should be adopted based on different situations ,so as to meet the requirements of specific testing tasks .
