近年来，用数值流形方法（NMM）解决岩石力学问题的尝试被认为是卓有成效的。本文将一个耦合的流体力学（HM）模型引入到扩展的NMM中来模拟岩石中的流体驱动破裂。在该HM模型中，采用“立方定律”来模拟通过裂缝的流体流动。几个基准问题进行了研究，以验证耦合HM模型。模拟结果与理论分析和实验结果吻合较好，表明耦合HM模型能够可靠、正确地模拟水力压裂过程。
Recent attempts to solve rock mechanics problems using the numerical manifold method (NMM) have been regarded as fruitful. In this paper, a coupled hydro-mechanical (HM) model is incorporated into the enriched NMM to simulate fluid driven fracturing in rocks. In this HM model, a “cubic law” is employed to model fluid flow through fractures. Several benchmark problems are investigated to verify the coupled HM model. The simulation results agree well with the analytical and experimental results, indicating that the coupled HM model is able to simulate the hydraulic fracturing process reliably and correctly.
