| 摘 要： | 非线性有限元正交设计算法，是借助于回归分析，用正交多项式拟合各岩石力学特性参数与各单元滑移面及岩体整体滑动安全余量间的函数关系，以评判边坡工程的可靠性。该法较蒙特卡罗法精度高，能满足工程计算的精度要求，且方法简单、计算时间少，不需改变有限元法的有关方程和计算程序，易为人们接受。

| Abstract: | The non-linear finite elermt orthogonal calculation is a method for evaluating the reliability of slope engineering by way of fitting the mechanical parameters of rock and the function relation between slide safety margin of element sliding faces and that of rock mass with orthogonal multinomial base on regression analysis. With simple sequence, less time consuming, easy to learn and more accurate than Monte-Carlo method, this method can satisfy the precision of engineering calculation without changing the equations and calculating sequence used in finite element analysis. |
