中文摘要：
考虑融雪人渗对顺层岩质边坡层理问力学形态的影响，基于Ubiquitous—Joint模型理论和融雪人渗边坡岩体的渗流特性，提出了一种适应边坡抗滑稳定的连续介质饱和非饱和渗流有限元模型，较好地描述了岩体层理面横观各向异性力学特性，并研究了模型数值实现方法及其计算收敛准则。通过工程实例中对某顺层岩质边坡融雪人渗失稳问题进行比对分析，证实了该理论研究的正确性和有效性，并就积雪深度、岩体层理面倾向和倾角对顺层岩质边坡稳定进行了多因素影响分析。同时，文中所建分析模型可推广应用于逆层岩质边坡和碾压混凝土坝层面等稳定分析。
英文摘要：
Considering the mechanical form of rock bedded slope under snowmelt infiltration, a finite element model on continuum saturated-un- saturated seepage in bedding rock slope is proposed based on the Ubiquitous-Joint model and the seepage characteristics of rock slope snowmelt infiltration. The model is adopted for its ability of describing the transversely anisotropy behavior of rock bedded slope. Meanwhile, its numeri- cal realization and convergence criteria are also studied. Comparison the results of a concrete seepage problem of bedding rock slope under snowmelt infiltration shows that the proposed model is correctness and effectiveness. The influence of snow cover thickness, tendency and incli- nation of rock bedding plane on the stability of slope are analyzed. This model can be extended to the stability analysis of reverse bedding slope and roller compacted concrete dam surface.
