摘要
盾构隧道在设计前期需要进行大量工况的隧道管片内力计算,计算时采用梁—弹簧模型可以较为接近实际情况,但采用该模型需要使用有限元软件实现,建模计算过程非常复杂。为了简化盾构隧道管片内力的建模分析过程,文章对Abaqus及其二次开发功能进行了介绍,基于Abaqus有限元软件内嵌的Python脚本语言和前处理接口进行二次开发,实现盾构隧道管片内力建模计算的自动化、参数化,并通过实例证明二次开发极大地提高了分析效率。
In the early stage of shield tunnel design, a lot of calculation must be done according to different situations. Beam-spring model is often used for the calculations, but it needs the help of FEM software and the process is time con-suming. In order to make the calculation of shield tunnel segments easier, the authors develop a calculation plugin based on the script language Python embedded in Abaqus. The engineering practice proves that the calculation plugin develop-ment is efficient and can make the calculation process parameterized and automatic.
