摘要
文章基于Bishop条分法分析的基本思想,建立了边坡可靠度分析计算模型,并采用有理多项式技术计算功能函数的偏导数,以模拟实际工程中常见的功能函数不能明确的可靠度计算问题。对于功能函数无论是线性或非线性,显式或隐式,该方法都简单且适用。数值结果表明该方法具有较好的效率和精度。
Based on the Bishop slice method, a calculation model is established for the analysis of slope reliability, and the rational polynomial technique is adopted to calculate the derivatives of the performance function at the design test point so as to simulate the reliability problems with the closed-formed performance function in actual engineering. No matter whether the performance function is linear or nonlinear, explicit or implicit, this method is simple and suitable. The calculation results of the reliability index show that this method has good efficiency and accuracy.
