| 摘 要： | 本文运用复合反演的观点研究结构参数未知条件下的地震动反演问题。根据地震作用的力学特性，将其具体化为估计输入的修正条件，文中给出了一类反演算法。理论分析及算例表明，该算法具有稳定的收敛特性以及良好的反演效果。

| Abstract: | By introducing composite inversion ideas,the problem of ground motion inversion is studied in this paper.According to the mechanical characteristic of earthquake effect,a new method named as statistical average algorithm (SAA) is presented.The validity of the method is proved by both theoretical analysis and numerical simulation,which make the utilization of this algorithm more reasonable. |
