摘　　要：渗流分析对大坝安全稳定具有重要意义,在进行大坝工程设计时,必须建立坝基中的渗流与应力的相互关系更能符合实际情况。文章基于裂隙岩体等效连续介质渗透原理,建立大坝二维有限元模型,有限元计算分析分布密集型岩体裂隙的二维非稳定渗流场与应力场耦合现象,提出在实际工程中考虑渗流应力耦合必要性和合理性。Seepage analysis is of great significance to the safety and stability of the dam.It is necessary to establish the relationship between seepage and stress in the dam foundation as carrying out the design of dam project.In this paper,based on the principle of equivalent continuous medium permeability of fractured rock mass,a two-dimensional finite element model of the dam was established to calculate and analyze the coupling phenomenon of two-dimensional unsteady seepage field and stress field of fractured rock mass with finite element method.The necessity and rationality of considering the coupling of seepage stress in practical engineering were proposed.
