| 摘 要： | 在水闸地基整体稳定性研究中,选择弹塑性大变形有限元进行计算。采用Updated Lagrangian法的有限元模型,用Fortran语言编制了相应的计算程序,计算有斜向荷载及渗透力并考虑了土体自重情况下的水闸地基稳定性。结果与弹塑性小变形有限元法对比,说明用弹塑性大变形有限元法计算地基土体稳定是合理和安全的。

| Abstract: | For investigation of the whole stability of sluice foundation, large deformation elastic-plastic finite element method was used to calculate. Adopted the Updated Lagrangian finite element model, the calculation program of foundation stability was compiled with Fortran, the whole stability of sluice foundation was computed in oblique load, seepage force and soil selfweight condition. The results of calculation were compared with small deformation elastic-plastic FEM, showing that it is reasonable and safe for the stability of sluice foundation to be computed by the large deformation elastic-plastic FEM. |
