摘要
本文介绍了一种具有多组节理系统的岩体的损伤张量的计算方法。根据能量原理,推导出了一个求解等效总体损伤张量的公式,适用于多个损伤张量求和。分析节理岩体强度的试验证实了计算结果。
This paper has presented a method for calculating the damage tensor of rock mass with mulit-set of joints. A formula to solve the equivalent global damage tensor by summing up the damage tensors of individual joint sets is derived based on the energy principle. A set of experiments to analyse the strength of jointed rock mass is used to verify the calculated results.
