| 摘 要： | 可用于模拟岩土介质系统工程响应性态的数学物理模型很多。就采用连续介质力学的原理而言，岩土力学基础理论研究发展了众多的本构关系模型，因而模拟计算分析的准确性与岩体本构关系的选择有关。本文研究直接利用岩体工程现场位移量测信息判别岩体粘弹性本构关系模型的原理和，岩体力学反演理论的一个重方面。算例分析表明本文所提方法有较大的工程应用价值。

| Abstract: | Model identification is an important aspect in the back analysis of rock mechanics inverse study. A study of the fundamental principle and approach to recognize constitutive laws of rock mass through adopting in-situ deformation measuring data is conducted. Case study shows the procedure and its powerful scope in practical application. |
