摘要
针对高桩码头的检测评估工作中缺少合理有效的评估方法和评估指标的问题,对结合干扰能量法的高桩码头结构评估指标进行研究。采用变分原理和最小势能原理,结合高桩码头的结构特点,建立基于干扰能量法的高桩码头结构整体安全评价的指标体系,并与现行规范进行对比。结果表明,此方法在评估局部构件的同时,还可定量给出结构的整体安全系数,能够反映不同构件对于整体安全性的贡献。
In order to solve the problem that it is lack of reasonable and effective evaluation method and evaluation index in the detection and evaluation of high pile wharf,we study the structural evaluation index of high pile wharf combining with disturbing energy method.By using variationally principles and principle of minimum potential energy,we establish the index system of overall safety evaluation for high pile wharf structure based on its structural characteristics combining with disturbing energy method,and compare with the current code.The results show that the method can give the overall safety factor of the structure while evaluating the local components,which can reflect the contribution of different components to the overall safety.
