节理型岩体损伤弹性的损伤力学算法
A Damage Mechanics Method of Calculation of Damage Elasticity for Jointed Rock
【摘要】 介绍了一种利用损伤力学方法计算具有均匀分布的节理型裂缝的块体的损伤弹性的方法 .损伤弹性矩阵的计算符合连续介质力学的对称、正定等一般原理 .将损伤弹性矩阵直接用于一般线弹性有限元的刚度矩阵便可对节理型块体用一般有限元方法进行力学分析 .与实验结果的比较证明了方法的合理性
【Abstract】 This paper introduces a damage mechanics method t o calculate the damage elasticity for jointed rock mass.The calculation method of elasticity matrix is in accordance with the principles of symmetry and positive definite i n continuum mechanics.The general finite element method can be used by employing the damage elasticity matrix in stiffness matrix.The comparison with experimenta l results shows the efficiency of the method.
