【摘要】 根据裂隙发育规模与工程尺度的关系，将裂隙岩体看作是由离散介质和拟连续介质组成的广义双重介质岩体，提出了广义双重介质岩体水力学模型，并对其有限元解法进行了较为详细的研究。其中对拟连续介质岩体的裂隙展布按分形理论进行模拟。最后以王庄矿３＃煤层的注水试验为算例，验证了该模型基本上是合理、可行的。更多还原

【Abstract】 Considering the scale of fracture and engineering, rockmass is treated as generalized double porosity media including discrete media and equivalent continuum. Its hydraulic model is put forward, and FEM solution is studied. U sing the fractal theory, the network of equivalent continuum is simulated. According to the example of water injection of Wangzhuang coal mine, the model is proved to be reasonable and effective.更多还原
