摘要
依据蠕变柔量和广义蠕变柔量概念，提出了由实测位移反演原岩应力场与粘弹性力学参数的边界元算法，实现了粘弹性围岩力学参数反演的半解析化。
A numerical method of parameter back analysis is presented for viscoelastic rock mass based on the creep compliance and the generalized creep compliance concepts. The model can be selected by the identification theory of the viscoelastic models and the rock parameters can be calculated by the semi analytical method proposed.
