摘要
根据裂隙岩体边坡渗流的基本特征和基本理论,阐述了离散元软件UDEC渗流—应力耦合的基本计算理论。利用UDEC作为分析平台建立数学模型,在考虑到渗流场与应力场耦合的作用下对裂隙岩体边坡的稳定性进行了全面分析。对边坡的应力、位移、渗流、裂隙分布等方面进行了研究,重点分析了在渗流与应力耦合的作用下边坡的变形破坏规律及自身稳定性。结果表明利用离散元软件UDEC分析流固耦合是一种有效、可行的方法,同时也为裂隙岩体边坡流固耦合方面的研究提供较高的工程应用价值。
According to the basic characteristics and basic theory of seepage flow in fractured rock slope,the basic calculation theory of seepagestress coupling of discrete element software UDEC is expounded. UDEC is used as the analysis platform to establish the mathematical model,and the stability of the slope of the fractured rock mass is analyzed comprehensively considering the coupling of seepage field and stress field. The slope stress,displacement,seepage and fracture distribution are studied. The deformation and failure of the slope and the stability of the slope are analyzed emphatically. The results show that it is an effective and feasible method to use the discrete element software UDEC to analyze the fluidstructure interaction,and also provides a high engineering value for the study of the fluid-solid coupling of the fractured rock mass slope.
