| 摘 要： | 针对目前低应变反射波法利用信息量不够的问题,从桩的振动和波动理论出发,推导出了桩土体系的理论模型,并对激振力和传感器特性进行了模拟,提出了利用波形拟合技术来定量分析桩身完整性,对工程桩进行了拟合分析,取得了一定的效果。同时对多解性问题进行了讨论。

| Abstract: | Aimed at solving the problem that the reflected wave method does not fully make use of the information received, this paper deduces the theoretical model of pile soil system on the basis of pile vibration theory and wave theory and also imitates exciting force and property of sensor. An effective waveform fitting technique is put forward to make quantitative analysis of pile completeness. The application of this technique to engineering pile has achieved good result. In addition, this paper discusses the multi solution problem. |
