Application of Computer Method in Solving Complex Engineering Technical Problems

In order to verify the applicability of computer numerical simulation method under complex engineering conditions, and solve problem that it is difficult guarantee normal construction underground projects with a depth more than 1 km (it carry out multiple field attempts high-depth if you simply use ordinary calculation method, its accuracy guarantee). For geological conditions an mine 1300 m in Central Plains China, based on finite difference (FDM) high accuracy, using FLAC $^{\mathrm {3D}}$ software FDM, progressive design (PDM), variety different schemes analyze mechanism force deformation surrounding rock mass project. Apply obtained optimal scheme actual engineering, monitor deformation. Comparing results monitoring results, show can also have good application ultra-kilometer depth. It provides theoretical basis technical guidance for hypothesis approximate conditions.
