| 摘 要： | 针对单层岩体板裂结构模型，在非线性弹性范围内推导了计算极限坡长Lcr的公式，并引入西原流变模型，在粘弹、粘塑性范围内将公式进行了修正，通过应用于分析雅砻江锦屏一级水电站三滩坝址Ⅰ右岸蠕变体的稳定性可见，计算结果与工程实际情况较为吻合，即提出的计算模型和极限坡长计算公式相对合理，具有一定的推广价值。

| Abstract: | In accordance with tabular structure model of along slope single layer rock mass, this paper developed a formulation for limit slope length calculation within the scope of non linear situation. The formulation was developed with rheological theory. As a practical engineering example, we analyzed the stability of the creeping mass on the right band of Santan dam site of Jinping Project. The result of computation shows that the model and formulation explained in this paper are reasonable and can be used in practical engineering. |
