【摘要】 基于土坝稳定渗流场与应力场的耦合关系,提出了稳定渗流方程和土体平衡方程的弱解形式,并根据该弱解形式和所设计的计算流程,按照有限元语言的语法规则,分别编写了线弹性土坝耦合场的全量算法和非线性弹性土坝耦合场的增量算法的脚本文件,借助有限元自动生成系统(FEPG)生成了FORTRAN有限元程序,并通过算例验证了本文所开发程序的正确性。更多还原

【Abstract】 Based on the coupling relationship of stable seepage field and stress field in earthfill dam,the integral weak forms of stable seepage equation and balance equation of soil are proposed herein,and then the script files of the total algorithm for the linear elastic coupling fields of earthfill dam and the incremental algorithm for the nonlinear elastic coupling fields of earthfill dam are respectively written in accordance with the integral weak forms of the equations and the designed calculation flow based on the grammatical rules of finite element language,furthermore,the FORTRAN finite element programs are generated by means of the Finite Element Program Generator( FEPG). Moreover,the correctness of the computational program developed herein is verified through the calculation cases concerned.更多还原
