摘要

针对含区域主干裂隙岩体在应力作用下的渗透特性进行了研究。运用单裂隙平行板渗流理论、弹性力学方法，结合模拟电路知识，提出等效渗流阻的概念。在分析裂隙岩体区域中主干裂隙系统几何构造的基础上，建立了基于等效渗流阻的- 渗流-应力耦合模型，得到了裂隙岩体等效渗流阻、渗透率与应力之间的关系，从而为研究含区域主干裂隙岩体的应力-渗流耦合规律提供了方便。结合一个基于等效渗流阻模型的算例，考察了含“人”字形组合裂隙试样的渗透特性。经进一步细化后，该模型可用于分析地应力作用下的含区域主干裂隙岩体渗流演化规律。

Abstract

Seepage characteristics of regional principal fratured rock mass are studied with the effect of stress. Using parallel plate model

elastic mechanics and electronics in single fracture

a new conception of equivalent seepage resistance is put forward. On the basis of the geometric construction of regional principal fracture

an equivalent seepage resistance model with seepage-stress coupling is established. With the model the relationships between equivalent seepage resistance

permeability and stress are obtained

which is helpful to the stress-seepage coupling characteristics of regional principal fractures in rock mass. Combining a case study with the model

the seepage laws of the herring-bone combined fracture are researched. Through further detail partition and consideration

this model can be used to study fracture seepage evolution law affected by in-situ stress in rock mass containing regional principal fracture.
