摘要
利用振动理论的系统识别法，建立“桩—土”系统动力模型，计算结果与工地现场工程桩的测试结果吻合较好；应用模态分析理论，综合了几何平均导纳、动刚度、波速等判据，对基桩常见故障的判别提出有效的方法。
Using systematic identification method of vibration theory, a pile-soil dynamic mechanic model is built and the calculating results are well fit for test results on engineering pile in the construction site. An efficient method is brought out on how to determine common problems of piles by applying Model Analysis Theory and referring to judging proofs such as geometric average admittance, dynamic stiffness, wave velocity and so on.
