摘要 为了提高大型有限元软件ABAQUS分析浅埋偏压隧道的效率，文章基于Python语言对ABAQUS前后处理进行二次开发，提出了程序开发的思路及一般步骤。基于此，研究了一种参数化计算程序，用于模拟不同的偏压角和埋深对浅埋偏压隧道稳定性的影响。后处理方面，实现了用户自定义的计算结果输出。应用开发的程序分析了偏压角在1°~40°及埋深在20~30 m情况下围岩、衬砌的变形受力规律。结果表明，所开发的程序能有效解决ABAQUS研究浅埋偏压隧道时前后处理中的重复性工作，提高了分析问题的效率。同时为基于Python的二次开发在其它领域中的应用提供了指导和借鉴。

Abstract： In order to improve the analysis efficiency of the large FEM software ABAQUS for shallow-buried unsymmetrical loading tunnels, the pre-processing and post-processing of ABAQUS is redeveloped based on Python language, and the concept and general steps of program development are presented. On this basis, a parametric calculation program is developed for simulating the effects of different unsymmetrical loading angles and buried depths on stability of shallow-buried tunnels. In terms of post-processing, the output of user-defined calculation results is realized; the redeveloped program is used to analyze the deformation and load rules of surrounding rock and lining under the conditions of 1°~40° unsymmetrical loading angles and 20~30 m buried depths. The results show that the redeveloped program can efficiently deal with the repetitive work in the pre-processing and post-processing of ABAQUS for studying shallow-buried unsymmetrical loading tunnels and improve analysis efficiency, providing a reference for the application of Python-based secondary development in other fields.
