软硬互层状岩体渗透特性研究

Research of Seepage Character of Soft and Hard Interbedded Rocks

叙述软硬互层状岩体中的裂隙发育规律,并由此建立了互层状岩体渗流的离散裂隙网络模型。根据裂隙网络水均衡原理,介绍了裂隙岩体网络渗流数学模型以及模型的求解方法;通过一个数值算例验证了模型的合理性,并且讨论了软岩中的切层裂隙以及软岩层面裂隙开度对渗流场分布和通过软岩流量的影响。

The article describes the regulation of the joint in the soft and hard interbedded rock, establishes a discrete joint network model of the interbedded rocks. According to the principle of water balance of joint networks, introduces a seepage mathemalical model for the network. By the calculation method of the model shows its rationality and discusses the affection of aperture of unstratabound joint and bed joint to the seepage and the flux through soft rocks.
