摘要:
依据现行规范中的反应位移法计算框架,利用通用有限元软件ABAQUS的二次开发接口,研发了针对盾构隧道横断面反应位移法的高效自动化计算软件ARCS(ABAQUS-Response deformationmethod of Crosssection System,简称ARCS)。该计算软件调用自行编制的一维地层地震响应等效线性分析程序,计算场地非线性地震响应;然后建立隧道横断面有限元模型,将地层相对位移、结构惯性力和结构与周围土层剪力等信息赋予模型并提交计算,完成后输出结构内力图,实现了整个流程的一体化及自动化操作。文中给出了Python语言与Fortran语言在ABAQUS环境下联合开发、ABAQUS中非线性弹簧自动定义、ABAQUS直接输出隧道结构内力图等问题的解决方法。结合某地铁盾构隧道典型横断面,对软件性能进行了验证,结果表明:该计算软件能够准确高效进行反应位移法模型求解。该软件有利于提高反应位移法的实际应用效率,对ABAQUS二次开发应用也具有一定参考价值。
Abstract:
Based on the calculation framework of the response deformation method in the current codes,this article uses the secondary development interface of the universal finite element software ABAQUS to develop an efficient automatic calculation software ARCS(ABAQUS-Response deformation method of Cross-section System,abbreviated ARCS)for the shield tunnel cross-section response deformation method.The calculation software first calls the self-developed one-dimensional seismic response equivalently linear analysis program to calculate the nonlinear seismic response of the site,and then constructs finite element model of the tunnel cross section,assigns the information such as the relative deformation of the site,the inertial force of the structure and the shear force between the structure and the surrounding soil to the model and submits it for calculation,and finally outputs the internal force diagram of the structure after completion. The whole process can be done automatically. Among them,to realize the integration of ARCS,this article presents solutions for the implementation of mixed programming in Python and Fortran in the ABAQUS environment,automatic definition of nonlinear springs in ABAQUS,and direct output of internal force diagrams of tunnel structures by ABAQUS.This article takes a typical subway shield tunnel as an example to verify the performance of the software,and the results show that the calculation software can correctly and efficienctly solve the problem through the response deformation method.This article is not only conducive to the widespread promotion of the response deformation method in practice, but also has reference value for the application of ABAQUS secondary development.
