摘要
从岩体裂隙网络渗流的特点出发 ,以岩体裂隙网络渗流与岩体应力相互影响、相互作用的耦合机理为基础 ,同时考虑裂隙网络渗流对裂隙壁施加的法向渗透压力和切向拖曳力 ,提出了裂隙网络岩体三维渗流场与应力场耦合分析的数学模型。
Based on the characteristic of fluid flow through the fracture network of rock mass, the mechanical mechanism of coupled fluid flow and stress is analyzed. The mathematical model for coupled analysis of the three dimensional seepage and stress fields in rock mass of fracture network is proposed. The model considers both the normal seepage pressure and the tangent hauling force of the fracture flow. Applying the mathematical model for the couple analysis, a computation example is also given to indicate the efficiency and applicability of the model.
