介绍了正交有限元试验分析方法的基本思想，并将其应用到地下工程设计方案优化中，得到了许多对工程有意义的结论；用该方法分析了某矿大洞室的锚喷参数优化和地下采场回采方案选取两个实际问题，证明该方法可以应用于处理地下工程设计中的方案优化问题。
The basic idea of the orthogonal finite element test analysis method was introduced and applied to the optimization of underground engineering design schemes. Many meaningful conclusions about the project were obtained; this method was used to analyze the optimization of the anchor-spray parameters of a mine’s large caverns. Two practical problems were selected for the underground stope recovery program, which proved that this method can be applied to deal with the optimization of the underground engineering design.
