边坡传递系数法是边坡工程设计中的重要计算方法,边坡传递系数法中边坡剩余下滑力计算的准确性和合理性决定了边坡工程治理的长期稳定性与治理的整体效果。然而现今许多文献及规范中根据不同边坡稳定性定义提出的计算方法,导致计算得到的剩余下滑力结果存在差异。本文通过对现有不同传递系数法稳定系数定义下推导出的稳定性系数及边坡剩余下滑力进行对比分析,得到了造成计算结果差异的理论依据,并通过实例证明了在实际工程运用中剩余下滑力的差异及其对设计计算造成的影响,针对计算差异提出了适用意见与建议。
The slope transfer coefficient method is an important calculation method in slope engineering design. The accuracy and rationality of the calculation of the remaining slip force in the slope transfer coefficient method determines the overall effect of long-term stability of slope engineering treatment and governance. However, the calculation methods proposed in many literatures and norms based on different slope stability definitions result in the difference of the calculated residual sliding force results. In this paper, by contrasting the stability coefficient and the residual slip force of the slope derived from the definition of the stability coefficient of the existing different transfer coefficient method, the theoretical basis for the difference of the calculation result is obtained, and the remaining evidences of the actual project operation The difference of sliding force and its impact on the design calculation, put forward the applicable comments and suggestions for the calculation of differences.
