| 摘 要： | 在有关地下巷道围岩的力学参数及初始地应力的反演问题中,线性逆过程法是求解这一问题的途径之一。本文根据逆过程法的基本原理,导出了以边界元法为基础的粘弹性位移反分析公式,并将其与以有限元法为基础的基本公式作了比较。文末的算例说明了二者之问的差别及各自的适用范围及实用性。

| Abstract: | In back analysis (BA) on the mechanical Parameters and initial stress of surounding rock for underground openings, linear inverse process is one of ways used to solve this problem. The back analysis formulas of viscoelastic displacements are derived from BEM according to the fundamental principle of inverse process, and it is compared with FEM BA formulas. Finally the Calculations illustrate the difference between them and their applicable ranges and practicalities respectively. |
