| 摘 要： | 为满足科研与生产的需要，基于有限元理论，推导了由现场位移观测值同时确定多种介质材料的物理力学参数的反分析模型。应用该模型进行的算例分析，表明了模型的正确性和有效性，且给出不同的初始值均能收敛到正确值。

| Abstract: | In other to satisfy the needs of scientific research and engineering, a finite element modeling based simultaneous displacement backanalysis approach is proposed to identify the physical mechanics parameters of multi-material.By using the approach ,two cases are studied and analysed,and the good and stable results of the cases are abtained, which prove that the modeling is correct and effective. |
