摘　　要：将有限元强度折减法与正交验设计相结合,用于嵩山隧道锚喷支护参数的优化,根据不同参数取值水平条件下有限元强度折减法计算的安全系数优选最佳锚喷支护参数,为工程设计和施工提供了理论指导.In this paper, the orthogonal experimental design method and the strength reduction finite element method are integrated and applied in the optimization of bolt-spray parameters of Songshan Tunnel. According to the safety factors calculated by using the strength reduction finite element method in consideration of different values of the parameters, the optimal values of bolt-spray parameters are given. The above analysis will give some theoretical guide to engineering design and construction.
