ANALYZING THE SAFETY OF DEEP EXCAVATION TUNNEL BASED ON DIFFERENTIAL EVOLUTION ALGORITHM AND 3D NUMERICAL SIMULATION

摘要：

The paper proposes an integrative feedback analysis method combining difference evolution algorithm, orthogonal design method and three dimensional numerical simulation. It could dynamically obtain the rock mechanics parameters and appraise the deep tunnel safety based on monitoring data. The integrative method and algorithm steps are discussed in detail. The proposed integrated method is used to back analyze the rock mechanics parameters and appraise the surrounding rock safety of the tunnels of Jin-Shan-Dian Iron Ore. The analyzing results have guide meaning to Jin-Shan-Dian Iron Ore production and indicates that the proposed method is feasible.
