| 摘 要： | 同一根桩由于激振设备的不同而定性为断桩、明显缺陷桩、合格桩三种结果。低应变反射波法检测桩身完整性,在易产生桩身浅部水平裂隙、预制桩的接头、混凝土灌注桩的低强区,应选用能激发出宽、窄两种脉冲的多种激振方法同时检测。

| Abstract: | The same pile would be tested as pile breaking,pile with obvious flaw,and qualified pile by using different vibration equipment.When testing pile by low strain reflection wave,we should use vibration equipment which can inspire wide,narrow pulses for pile that appears the shallow horizontal cracks at the pile body,the joint part of preformed pile and the low-strength part of concrete prefabricated piles. |

| Keywords: | pile testing by using reflection wave vibration equipment pulse maximum vertical displacement close crack β |
