项目摘要
To provide a set of governing equations for solving the coupled stress and fluid flow, a rock mass, which commonly contains a large number of geological discontinuities, is treated as an anisotropic, elastic porous medium with the corresponding elastic compliance and permeability tensors, hydro-mechanical equivalents to the discontinuous mass. The hydro-mechanical equivalents, with the special emphasis on the permeability tensor, are formulated on the assumption that cracks can be replaced by a set of parallel planar plates connected by two springs. Two-dimensional numerical analyses on seepage flow networks support the validity of the permeability tensor. Some field evidence is analyzed to examine the applicability of the present model for the practical purpose of rock hydraulics.
为了提供一组用于求解应力和流体流动耦合的控制方程,通常包含大量地质不连续体的岩体被处理为具有相应弹性柔量和渗透率张量的各向异性弹性多孔介质,流体力学等效于不连续体。流体力学等效,特别强调的渗透率张量,制定的假设,裂纹可以取代由两个弹簧连接的一组平行的平板。二维渗流网络的数值分析支持渗透张量的有效性。一些现场证据进行了分析,以检查本模型的岩石水力学的实用目的的适用性。
