| 摘 要： | 边坡工程具有大量不确定性因素,需要采用不确定性方法对其进行分析。通过对边坡稳定分析中不确定性因素的分析,提出了一种使用区间理论来计算边坡工程稳定性的新方法。这种方法可以考虑稳定分析中所涉及到的计算力学参数的不确定性。把区间数学和极限平衡法相结合,建立了区间极限平衡方法,推导了区间安全系数的计算公式。实例研究表明,边坡稳定性区间分析方法是一种更合理的边坡稳定性评价方法。

| Abstract: | The uncertainty method is applied slope engineeringSwithSlarge uncertainties. Considering theSuncertaintySfactors of theSslope stability analysis it proposes a new method to calculate the stability of the slope engineering using interval theory. The advantage of this method can consider the uncertaintySof the computational mechanics parameters. CombiningSthe interval mathematics and theSlimit equilibrium method,Sthe intervalSlimit equilibrium method is established and the calculation formula of the interval safety factor is derived.The case study shows that the slope stability of interval analysis method is a more reasonable method for evaluation of slope stability. |
