| 摘 要： | 本文利用文献中的数据进行数值模拟试验，结果表明：流量等效和渗透作用力变形效果等效互不包容；不同级别结构面体系难以用连续介质方法处理，同级别结构面体系在工程作用力变化范围内，可由其静态水力特征推演动态特征；工程岩体结构面间充分连通的假设过于粗糙，常规试验手段获取的量值倾向于局部特征的反映。

| Abstract: | The numerical simulation results show that equivalence in continuum model of fluid flow in fractured rock in terms of flux and seepage force’s deformation can not be deduced from each other; that continuum model is not applicable to fractures with the remarkable difference in hydromechanical features; but variation of its hydraulic parameters with stress can be easily obtained through the numerical simulation. Results from the field data indicate that it would be too rough to assume that fractures in rock are completely interconnected, and that in situ experiment result seems to reveal the behavior of fractured rock not on the RE V scale, but on the local scale. |
