摘　　要：为解决在役高桩码头在船舶靠泊时的响应预测预警问题,提高高桩码头的结构损伤监测和评估效率,基于某高桩码头实例,利用Midas/GTS NX软件建立了考虑桩-土相互作用的高桩梁板式码头三维有限元模型;研究船舶靠泊时的高桩码头结构失效模式并确定了响应面参数,建立了高桩码头结构响应的响应面方程;对响应面方程进行拟合优度检验、F检验和t检验,验证了方程的准确性,同时分析了各影响因素对不同结构响应的显著性;最后通过误差分析对高桩码头结构响应的预测结果进行评价。研究成果可以为高桩码头结构的响应预测提供借鉴。In order to solve the problem in predicting and warning the response of an in-service long piled wharf when a ship berths to it,and to improve the efficiency of monitoring and assessing the structural damage of a long piled wharf,a three-dimensional finite element model of a long piled beam-slab wharf considering pile-soil interaction was established based on an example of a long piled wharf using Midas/GTS NX software.The structural failure mode of a long piled wharf when a ship is berthing was studied and the response surface parameters were determined.The response surface equations for the structural response of a long piled wharf was established.Goodness-of-fit test,F-test and t-test were carried out to verify the accuracy of the equations and the significance of various influencing factors on the response of different structures was also analyzed.Finally,the predicted results of the structural response of a long piled wharf were evaluated through error analysis.The results of the study can be useful for the response prediction of long piled wharf structures.
