Abstract
The optimization design of the section morphology of large-span tunnels plays an important role for saving cost and improving the engineering stability. The flat ratio of tunnel which is as an important control index, its rationality is the key problem in the design of tunnels. Program with Python to set up the dynamic calculation model of a large-span tunnel planned to be constructed which can be run and analyzed in ABAQUS. The MATLAB language is used to compile the optimization analysis program based on genetic algorithm, and then the dynamic calculation model is embedded into it. Using excavation area, plastic zone, ground surface settlement, vault subsidence, etc. as optimal objective to make dynamic analysis for the model and put forward the reasonable flat ratio of the supported project. The result of this paper provides reference for the section optimization design of similar tunnel engineering.
