| 摘 要： | 提出了一种研究贯通节理岩体等效弹性参数的近似模型，导出了贯通节岩体基本弹性常数的解析估算公式，在此模型基础上编写了相应的较为通用计算程序，分析了多组节理的存在以及节理的倾角对岩体性能的影响，预测得到的节理岩体弹性矩阵和弹性常数与节理有限元数值方法的结果十分接近，是一种预测贯通节理岩体等效弹性参数的简单而实用的方法。

| Abstract: | An equivalent model analyzing elastic constants of jointed rock masses is presented by the method of material mechanics. The analytical formulas for estimating basic elastic constants of persistent jointed rock masses are derived. The corresponding common procedures are written and the effects of one or more sets of joints as well as the orientational angles of joints on the rock masses properties are analyzed based on the presented model. The equivalent elastic matrix and material constants predicated have a good agreement with the results by using the numerical method with joint elements. It is a simple and practical method for predicating the equivalent elastic parameters of jointed rock masses. |
