| 摘 要： | 针对目前国内外碎石桩复合地基抗液化判别方法的研究现状进行了简要归纳和分析 ,其研究结果表明 :已有的判别方法存在着较大的局限性 ,还不能很好地反映碎石桩的排水效应、减震效应及各效应的综合作用 ;桩径、桩长、桩距等加固参数对加固效果的影响还不能在判别标准中得到合理的体现。最后 ,笔者对今后的研究工作提了几点建议

| Abstract: | Recent advances in anti-liquefaction judgment method for stone column composite foundation were reviewed and analyzed. The study shows that some existent judgment methods were rather limited. Drainage effect, focusing stress effect and comprehensive effect were not being reflected. The influence of reinforcement parameters such as diameter, length of stone columns and the spacing between columns on reinforcement effect were not being embodied reasonably in judgment criteria. Finally, suggestions are made about future studies. |
