摘　　要：利用有限元软件构建弯沉盆数据库的工作量庞大,费时费力,阻碍了弯沉盆反算工作的深入开展。利用Python语言对有限元软件进行二次开发,实现了计算机自动计算并输出弯沉盆数据,所需时间仅为人工逐一更改路面结构参数构建弯沉盆数据库的1/4,并且随着计算机性能的提升,效率亦会进一步提升。该方法省时省力,结果可靠,足够的效率使科研工作者在弯沉盆数据库的构建时可以考虑更丰富的路面结构组合情况,为弯沉盆反算的前期工作提供了有力支撑。The work of using finite element software to construct the database of the deflection basin is huge,time-consuming and labor-intensive,hindering the further development of the back-calculation of the deflection basin.The secondary development of finite element software by using Python language makes it possible for computer to calculate and output the data of the deflection basin automatically,which takes only one-ninth of the time used for manually changing the pavement structure parameters to construct the database of deflection basin,in addition,computers with better performance could further enhance the efficiency.With high efficiency and reliable calculation results,and the improvement of efficiency allows researchers to consider more conditions during the construction of database;this method could be a strong support for the preliminary work in the back-calculation of deflection basin.
