摘要
在基桩低应变法动力测桩中,能否采用速度传感器对桩身浅部缺陷进行有效检测,尚有一定争议。基于此,论文对速度传感器的频响特性进行研究分析,并结合多项工程的检测实践,论述了在正确选用速度传感器、合理选择检测工作方法的条件下,用速度传感器检测基桩的浅部缺陷,完全可以取得很好的检测效果。
It is still controversial whether the velocity sensor can be used to detect the shallow defects of pile body effectively in low strain dynamic test pile.Based on this,this paper studies and analyzes the frequency response characteristics of speed sensor,and combined with the testing practice of many projects,discusses that the shallow defects of foundation piles can be detected by using speed sensors under the condition of correct selection of speed sensors and reasonable selection of testing methods.
