【摘要】 作为基桩完整性检测的常规方法,低应反射波法因为野外数据采集快,成本低,效率高,便于大面积普查等优点,而在基桩完整性检测中得到广泛应用。但在实际检测中往往由于不严格按骤步进行检测或采用方法不当等原因,而使实测波形不能真正反映基桩的实际情况,因而造成错判、误判等,严重影响了工程质量和施工单位的正常工作。介绍了反射波法检测基桩完整性的几个步骤,并着重提出了现场检测中的一些注意事项。更多还原

【Abstract】 Low-strain reflected wave method,which was a conventional method with long history,had been introducted to state criterion.This method had many advantages,such as field data acquisition quickly,low costs,high efficiency and large area census expediently.Thus it had been applied widely to detection of foundation pile perfection.In practice,field measured wave without stick procedures couldn’t reveal actual situation so as to cause error judgement and delay construction.In this paper,with author’s long work experience,procedures and method of detection of perfection foundation pile by reflected wave method are introduced and points for attention is put forward in site detection更多还原
