| 摘 要： | 本文在对侏罗系砂溪庙组砂，泥岩进行的系统流变试验的基础上，详细研究了砂，泥岩的流变特性及其相应的长期强度，以及砂，泥岩互层状组成的斜坡碉体流变特征，特别是模拟研究了风化深度较厚的泥岩产生的粘塑性流动对斜坡应力场及斜坡变形破坏所起的不可忽视的作用。

| Abstract: | Based on the results of systematic tests, The rheological properties and the related longterm strength of sandstone and mudstone of Jurassic Shaximiao Formation are described in detail in this paper. The rheological features of slope rockmass composed of alternating beds of samdstone and mudstone are also studied with numerical simulation. The viscoplastic deformation in weathered mudstone is discovered to play an important role in the development of stress field and in the deformation and failure of slope. |
