| 中文摘要: |
| 地下工程空间分布优化设计是大型地下工程稳定性分析的关键。如今，制约其发展的瓶颈主要有两个：一是模型的建立；二是优化方法的实现。针对以上问题，以大型有限元软件ABAQUS为平台，基于其标准设计语言Python对其前后处理进行二次开发，将参数化模型可动边界的非线性关系编入到程序中，实现了有限元参数化设计；通过MATLAB语言编程，建立基于Nelder-Mead法与精确罚函数法的联合优化方法，并将优化分析程序与有限元参数化设计相结合，实现了地下工程问题的“智能连续”优化。文中涉及到工程应用将在本文的Ⅱ部分给出。 |

| 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
fem-based 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. |
