| 中文摘要: |
| 通过对某尾矿坝进行ABAQUS二维建模,运用了修正Mohr-Coulomb破坏准则建立了在降雨入渗条件下坝体的非饱和土流固耦合有限元计算模型；通过采用合适的土—水特征曲线得到了非饱和边坡变形与应力的若干模拟结果并与实测结果进行对比分析.研究成果为继续研究尾矿坝在降雨入渗条件下的稳定性分析提供了基础. |
| 英文摘要: |
| Flow-deformation coupled unsaturated soil model is built based on rainfall infiltration condition and modified Mohr-Coulomb failure criterion according to modeling a tailing dam with ABAQUS software.A few conclusions are obtained by adopting proper hydraulic curve soil water characteristic curve and compared with actually measured data.Study yields provide foundations for simular analysis on tailing dam on the condition of rainfall infiltration. |
