| 摘 要： | 通过将黄土的孔压增长模型用于碎石桩黄土地基的地震液化有限元数值分析 ,表明地震过程中黄土的孔隙水压力增长很快 ,震后消散缓慢 ,并伴随有大的沉降量。碎石桩的抗液化 (排水 )效果明显 ,但范围有限 |
| 关 键 词： | 饱和黄土地基 液化 孔隙水压力 有限元 |

| Abstract: | In the paper, the pore water pressure generation model of loess was first applied to the finite element numerical analysis of earthquake liquefaction in loess improved by gravel piles. The calculation results show that the pore water pressure in a saturated loess increased very rapidly during earthquake and dissipated slowly after earthquake and that the large settlement was induced. The anti liquefaction(draining water) effect of gravel piles is obvious, but the tributary area to gravel pile is limited. |
| Keywords: | saturated loess ground liquefaction pore water pressure finite element |
