摘　　要：通过建立高桩码头基桩物理模型,进行了模态试验和基于ANSYS的模态分析,结果表明:高桩码头基桩模态参数有限元模拟结果与模态试验识别结果吻合较好,验证了数值模型建立方法的正确性和高桩码头基桩模态参数基于随机子空间识别方法的可行性。Physical model of high-piled wharf piles is established. Model test and finite element numerical analysis of high-piled wharf piles are studied, the resuhs of research show that high-piled wharf piles modal parameter identification based on the Stochastic Subspaee Identification （ SSI ） is close to the finite element simulation results. It proves that modal parameter identification of the high-piled wharf piles based on Stochas- tic Subspace Identification （SSI） and the finite element model of the high-piled wharf piles are correct and reliable.
