黄河上游某巨型倾倒体主要由反倾层状砂岩和板岩相间分布构成，砂岩层以倾倒拉裂为主，板岩层以弯曲变形为主，两种不同的时效变形组合导致整个倾倒体的演化具有长期性、累进性和阶段性的特征。基于岩体组合模式和变形破坏表现形式，研究两种岩层的时效变形空间分布特征，总结整个坡体的时空演化规律，并探究其成因机理，论述岩体组合模式、岩体结构、卸荷裂隙以及地形地貌等因素对倾倒体演化的影响。

This paper examines a large scale toppling rock slope on upper reach of the Yellow River.It is alterna-tively composed of countertendency bedded sandstone and thinly bedded slate.There are mainly tension cracks in the sandstone and flexural deformation in the slate.As a result of the combination of the two different time-depend-ent deformations,the evolution of the whole toppling rock slope is characterized as long-term,slow and progressive. Based on the combination mode of rock masses and the form of the deformation and failure,the space distribution features of the time-dependent deformation in the sandstone and slate are presented.The temporal and spatial evolu-tion character is summarized.The mechanism of the evolution is researched.The influence of the combination mode and the structure of the rock masses as well as unloading fissure and landform during the evolution of the toppling rock slope are discussed.
