Application of Computer Method in Solving Complex Engineering Technical Problems

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