【摘要】 通过对岩石蠕变模型的分析表明西原模型可以作为岩质边坡蠕变分析模型,该模型能较好的反映岩质边坡蠕变特性,有利于解释边坡蠕变破坏机理。针对层状岩质边坡的实际情况,论文将Patton准则用于岩质边坡中得出了考虑不连续面剪切特性的蠕变强度准则,为边坡安全度预测提供了一个有效的途径。更多还原

【Abstract】 Bingham- Kelvin model is regarded as a creep analysis model of rock slope that was derived byanalyzing and comparing the creep models of rock, it represents the creep features of rock slope better andexplains the creep failure mechanism of slope. With respect to the bedded rock slope, the authors here apply thePatton principle and have suggested a shear strength creep principle that considering the shear features of thediscontinuity in rock slope.Considering the change of safety of slope with time,the shear strength creep principlecan be applied to predict the safety factor variation with time.更多还原
