摘要：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. ©, 2015, Editorial Office of "Modern Tunnelling Technology".
