摘　　要：针对混合坝坝体边界较复杂致使边界条件施加困难,从而增加渗流计算难度的问题,利用大型通用有限元软件ABAQUS提供的用户子程序,对ABAQUS进行二次开发,对某混合坝不同坝型接触面进行渗流计算时,采用Fortran子程序对其施加孔压边界条件并进行渗流场分析。结果表明,该混合坝的防渗安全满足要求,进而证明提出利用二次开发施加边界条件可行。In the seepage analysis of practical engineering, imposed boundary condition becomes very difficult because of complex boundary conditions of the dam. Therefore, it increases the difficulty of seepage analysis. To solve this problem, by using the user subroutines in ABAQUS finite element software, the secondary development of ABAQUS is implemented. In a mixed dam seepage analysis, this paper uses the Fortran subroutine to impose pore pressure boundary conditions and analyzes its seepage field. The results show that the safety of seepage control of the mixed dam meets the requirements. Thus, it is proved that the proposed boundary conditions imposed by secondary development is feasible.
