【摘要】 对于带有普查性的灌注桩完整性检测,低应变反射法较为便利和经济。低应变反射法检测过程包括三大技术步骤:信号采集技术、波速确定技术和缺陷判断技术,三步骤环环相扣,均对检测效果有重要的影响。结合实践工程桩,应用低应变反射法对桩身完整性问题做出综合评价,对各代表性类型的工程桩做出判断分析。更多还原

【Abstract】 It is convenient and economic to use the low-strain echo method in examining the integrality of pour-pile outright. The examining process consists of three interactional technical steps: collecting the signal, ascertaining the wave speed and judging the disfigurement. These factors affect the examining precision. The integrality problem of actual pour-pile is analysed synthetically with the use of he low-strain echo method. Subsequently, the representative types of the familiar pile’s disfigurement are examined and analysed.更多还原
