摘要:
基于传统强度折减法,提出部分强度折减法思想结合不平衡推力法,简述相关计算方法及物理意义,应用白果树滑坡模型分析该滑坡目前的稳定性系数和可能的渐进破坏稳定性系数。研究结果表明:部分强度折减法相对于传统强度折减法更能够近似反映出滑坡的渐进破坏发展趋势,临界状态点在逐渐前移的同时,相关不平衡推力也对应着逐渐增大,且当临界状态移动至最后一条块时,经计算所得出的稳定性系数即是滑坡的整体稳定性系数。
Abstract:
Based on the traditional strength reduction method, this paper puts forward the idea of partial strength reduction method combined with unbalanced thrust method. It first briefly describes the related calculation method and physical significance, and then combines the model of Baiguoshu landslide. The present stability coefficient and the possible progressive failure stability coefficient of the landslide are analyzed. The results show that the partial strength reduction method can reflect the progressive failure trend of the landslide more approximately than the traditional strength reduction method, and that the corresponding unbalanced thrust increases gradually as the critical state point advances gradually. The results also show that the partial strength reduction method can reflect the progressive failure trend of the landslide more approximately than the traditional strength reduction method. When the critical state point moves to the last block, the calculated stability factor is the overall stability factor of the landslide.
