【摘要】 基于全量补偿复合反演算法,对孤立墩柱在波浪力部分输入信息未知条件下,分别对无噪声和有噪声干扰的情况进行桥梁墩柱结构的物理参数识别及波浪时程反演研究。算例数值分析表明,结构物理参数识别结果满足精度要求,对墩柱在部分未知输入信息下的参数识别的反演方法是可行的。从而为跨江、跨海墩柱受波浪力作用下的结构物理参数识别研究提供了一种新的方法,供工程应用参考。更多还原

【Abstract】 The total compensation composite inversion algorithm based on isolated pier,wave forces on a portion of the input information is unknown,respectively,to the absence of noise and study history inversion noise condition for physical parameter identification and wave bridge pier column structure.The numerical analysis shows that,the structural physical parameter identification results meet the accuracy requirements,inversion method for parameter identification of pier column in the input part information under unknown is feasible.It provides a new method for the identification of structural physical parameters of cross river,sea pier column under wave force,a reference for engineering application.更多还原
