目前裂隙合体中水的流动均采用相似连续或不连续离散模型进行模拟。本文推荐一种离散──连续流的耦合模型、来模拟裂隙合体近区及远匠的水流情况。例如在大坝建设或隧道开挖工程中,近区用高散流时、水仅通过内连的裂隙,而在远区则采用相似连续流、同时采用边界积分公式方法。对地下隧道或大坝基础岩体、临近区域的任一水流情况,用不连续流模型就可解决此类问题。文中数据实例及工程应用、表明此法基础研究的潜在功能。这种方法的效益也可由其在大坝基础问题应用中表明。
At present, the flow of water in the fissures is simulated by using continuous or discontinuous discrete models. In this paper, a discrete-continuous-flow coupling model is proposed to simulate the water flow in the vicinity of the fissure and in the far-stream. In dam construction or tunnel excavation, for example, when high water flow rate is used in the near area, water only passes through the interconnected cracks, while in the far area, a similar continuous flow is adopted and the boundary integral formula method is used. For any water flow in an underground tunnel or dam foundation rock mass or adjacent area, a discontinuous flow model can solve such problems. The data examples and engineering applications show the potential of basic research in this method. The effectiveness of this method can also be demonstrated by its application to the dam foundation.
