裂隙基岩渗透张量反分析及等效连续介质模型

对裂隙介质渗流理论在实际工程中的应用作了尝试和研究。由大坝原型观测资料对坝基的渗透性作了反分析，得到了基岩的裂隙张开度及渗透张量，并对裂隙介质与连续介质的等效条件作了探讨。离散模型和等效连续介模型的计算结果与实测资料较为吻合，验证了所得的渗透张量是合。计算所采用的理论和方法对类工程具有参考和推广价值。

Back Analysis of Permeability Tensor of Fractured Rock Mass and Equivalent Continuum Model

he back analysis of the permeability of dam foundation with the theory of fluid flow in rock fractures is described in this paper. The fracture aperture and permeability tensor are investigated numerically.Both the discrete model and the equivalent continuum model give satisfactory results compared to prototype observation data,thus,the permeability tensor obtained is reasonable for the dam foujidati on and the techniques presented here can be applied to other similar engineering projects.
