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。
The nonlinear finite element orthogonal design method is based on regression analysis and orthogonal polynomials to fit the relationship between mechanical parameters of rock and the sliding surface of each unit and the overall sliding safety margin of rock mass to judge the slope engineering The reliability. Compared with the Monte-Carlo method, this method can meet the precision requirements of engineering calculation. It has the advantages of simple method, less calculation time and no need to change the relevant equations and calculation procedures of finite element method.
