It is convenient and economic to use the low-strain echo method in examining the integrality of pour-pile outright.
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。
Testing bearing pile with low strain method will be some defects in the bottom if the echo from the tip has the same phase as the pulse at the top.
用低应变法检测嵌岩桩,若桩底出现明显同相反射,多数因桩底缺陷引起。
Pulse Echo method (PEM) is a fast, economic and feasible method for Low-strain Dynamic Testing (LDT) of piles.
小应变反射波法是当前在工程桩基检测中应用的动测法之一。
