摘要:
长期以来对于边坡稳定性分析采用极限状态理论,该方法对条块以及力的传递作了一定简化,会影响结果的严密性。采用一种新的稳定性分析方法,以鹤峰县县城东街斜坡治理为例,根据边坡现场实际情况,应用新的渐进破坏不平衡推力法并结合一种新的本构模型对边坡进行稳定性分析,由此计算滑坡稳定性系数。研究结果表明:改进的不平衡推力法其稳定性系数要小于传统条分法计算的稳定系数,可以真实地反映出滑坡的稳定性情况。
Abstract:
The limit state theory has long been used for slope stability analysis, which simplifies the transmission of strips and forces, and is prone to affect the rigor of the results. In this paper, a new stability analysis method is therefore adopted by taking the slope treatment of Dongjie in Hefeng County as an example. According to the actual situation of the slope site, a new progressive failure unbalanced thrust method and a new constitutive model are applied, by which the stability of the slope is analyzed, and the stability coefficient of the landslide is calculated. The results show that the stability coefficient of the improved unbalanced thrust method is smaller than that of the traditional slice method, which can truly reflect the stability of the landslide.
