中文摘要：

这份报纸试图借助于 homogenization 方法决定连接岩石群众的力量性质。为了反映连接岩石的微观结构，集中，代表性的元素体积(加快) 被选择。假设僵硬、非常塑料并且利用 Mohr 库仑为岩石和关节产出标准，一个上面的界限限制分析方法基于 homogenization 理论被建议。由使用有限元素方法和 Goodman 联合元素，有平等限制的非线性的数学编程被提出，它能被一个直接反复的算法解决。数字结果证明连接岩石群众的力量表现有不同联合方向的 anisotropy。这个方法为连接岩石群众的力量分析介绍一个有效工具。

英文摘要：

This paper aims to determine the strength properties of jointed rock masses by means of the homogenization method. To reflect the microstructure of jointed rock masses, a representative element volume （REV） is selected. Assuming being rigid and perfectly plastic and utilizing the Mohr-Coulomb yield criterion for rock and joints, an upper bound limit analysis method is proposed based on the homogenization theory. By using the finite element method and Goodman joint element, a nonlinear mathematical programming with equality constraints is formulated, which can be solved by a direct iterative algorithm. Numerical results show the strength of jointed rock masses behaves anisotropy with different joint directions. This method presents an effective tool for the strength analysis of jointed rock masses.
