本文结合本钢南芬铁矿岩石胶带运输系统1号驱动站大硐室的锚喷支护参数优化问题，成功地将正交设计的思想引入到数值模拟中，用正交有限元试验方法将支护参数的选取对工程稳定性的影响进行了评价，给出了以顶底板相对位移、边帮移动量及塑性区面积为评价指标时锚杆长度、喷层厚度以及喷层弹性模量的最佳参数值，为工程设计提供了理论指导。
Combining with the optimization of bolting and shotcreting parameters in the large chamber of No. 1 drive station of the rock belt conveyor system in Benfang Nanfen Iron Mine, the idea of orthogonal design was successfully introduced into the numerical simulation. The orthogonal finite element method The influence of the support parameters on the stability of the project is evaluated. The relationship between the length of the anchor rod, the thickness of the sprayed bed and the elastic modulus of the sprayed layer is given with the relative displacements of top and bottom plates, The best parameter value provides theoretical guidance for engineering design.
