Abstract: The optimization design of underground engineering space distribution is the key of stability analysis in a large-scale underground engineering. Nowadays,there are two main bottlenecks to restrict its development. One is the problem of model establishing and the other is the implementation of the optimization method. Taking the general-purpose finite element software ABAQUS as a platform,its standard design language Python is used to make secondary development for the pre-processing and post-processing. The moving boundary nonlinear relationship of parametric model is made into the program to realize the fembased parametric design. Using MATLAB language for programming,a combined optimization was established on the basis of Nelder-Mead algorithm and exact penalty function method,and further combining the optimum analysis program with finite element parametric design,the intelligent and continuous optimization method in underground engineering has been realized. The engineering application involved in this paper will be given in Part Ⅱ of this paper series.
