【摘要】 为了对强夯黄土地基震陷性进行较为直观合理的分析,基于离心模型试验定量评价了强夯黄土地基抗震性能。试验结果表明:黄土地基含水率是影响强夯处理效果的重要因素,水平层强夯程度所存在的差异性对黄土地基的震陷量的影响不是很明显,强夯法处理黄土地基在有效深度范围内可以完全消除黄土地基的震陷性。更多还原

【Abstract】 Based on centrifugal model tests,the effect of dynamic compaction on the secimic resistance of loess ground was quantitatively evaluated.It was shown that the moisture content was an important factor which influenced the effect of dynamic compaction on the secimic resistance of loess ground,and there was little influence caused by the difference of degree of dynamic compaction in the same level of soil layer.The dynamic compaction of loess could completely eliminate the seismic subsidence within a certain effective depth.更多还原
