| 摘 要： | 为了研究低应变反射波法对管桩裂缝的检测效果,更好地识别和检测出裂缝的类型和位置,文章对模型桩进行了理论计算和检测实验,了解管桩中波传播的特征;通过制作完整PHC管桩和一系列缺陷桩(包括横向裂缝、竖向裂缝及斜向裂缝),采用低应变反射波法测得了数百条测试曲线;对理论曲线以及实测曲线进行了分析,得到了一些有意义的结论。

| Abstract: | In order to study the effect of low strain integrity testing on the detection of the pipe pile cracks and better identify the type and location of cracks,the theoretical calculation and detection experiments of a model pile are carried out.The characteristics of wave propagation in the pipe pile are presented.By making intact PHC pipe piles and several defective piles with horizontal cracks,vertical cracks and oblique cracks,hundreds of testing curves are obtained by the low strain integrity testing.Several useful conclusions are drawn by the analysis of theoretical curves and measured curves. |
