利用不平衡推力法分析昭山地区边坡稳定性
Using Imbalance Thrust Force Method to Analyze the Slope Stability in Zhaoshan Area
摘要
Abstract
As an important method for stability evaluation of slope project, the imbalance thrust force method has been widely used in engineering practice. In the process of using the imbalance thrust force method to evaluate slope stability, as the transfer mode of the force in different failure modes, that is pull-type failure mode and push-type failure mode, is different, the calculation method of safety factor is different, too. In this paper, through introducing the theory of slices method and supposing that the direction of the interaction force among each sticks behave conformity, the corresponding calculation formula connected with safe factor of a slope is derived based on the equilibrium relationship between the force and the moment with respect to each sticks, under the circumstances of two different failure modes. The comparison results of safety factor between two different failure modes are shown according to a slope instances. It demonstrates the importance of the failure modes during the stability evaluation of a slope by taking advantage of the imbalance thrust force method.关键词
