摘要
根据三维实体单元的弹塑性理论,借助Fortran95语言具有模块分析、数组运算和多重继承等编程语言的特性,在线弹性有限元程序的基础上开发非线性阶段的三维实体单元应用程序,通过探索非线性三维实体单元有限元算法的同时为地基沉降的计算提出一种精确、高效的计算方法。通过该方法结合工况修订参数,采用程序运算计算结果,最后,通过使用本程序和SAP2000、ANSYS商业软件计算模拟地基沉降值进行对比分析,验证程序的可行性和精确性。
In this paper,based on the elastic-plastic theory of three-dimensional solid units,we develop a threedimensional solid unit application in the nonlinear phase based on the on-line elastic finite element program by using the characteristics of Fortran95 language with modular analysis,array operations and multiple inheritance,and propose an accurate and efficient calculation method for foundation settlement by exploring the nonlinear three-dimensional solid unit finite element algorithm..Through this method,the calculation results are calculated by combining the revised parameters of the working conditions and using the program,and finally,the feasibility and accuracy of the program is verified by using this program and SAP2000 and ANSYS commercial software to calculate the simulated foundation settlement values for comparison and analysis.
