摘要
介绍了函数连分式方法在斜坡稳定性概率评价中的应用,该方法可方便容易地计算出状态函数对各随机变量的偏导数,从而使传统的安全系数方法和概率评价有机地结合,相互补充。文中给出了研究实例。
Application of continued fraction approximation method to slope probabilistic analysis is developed. The partial derivatives of the performance function with respect to random variable can be calculated easily with this method. The traditional safety factor method can be combined with probabilistic analysis and be complemented each other. An example is given.
