节理岩体损伤变量确定的分形方法

Study on Fractal Method of Damage Parameter in Discontinuous Rock Mass

针对节理岩体损伤张量采用统计概率模型确定存在问题，首先建立了岩体结构分维与波速的关系方程，验证了采用分维数进行岩体质量评价的可行性，然后提出了采用室内岩块波速值与岩体结构分维确定节理岩体损伤变量的分形方法。

The problems of determination of damage tensor with statistics-probability model are analysized firstly, and the relation between fractal dimension of rock structure and wave velocity is built up. Then the feasibility of rock mass quality evaluation by fractal dimension is vertified, and a fractal method of rock damage parameter is advanced.
