摘要
针对不同桩型,不同密度的砂土进行相对埋深(H/D=4)的室内模型桩试验分析。观测桩周端土体的应力情况,然后导出其附加应力与外荷的关系曲线,并进行了砂土体破坏原理的分析。
With different types of pile and various sand densities, indoor model pile tests and analyses are proceeded under relative burying depth H/D = 4. The stress condition of the soil mass around pile tip-side is observed, and additional stress-load curves are plotted. Then the mechanism of sand mass destruction is discussed.
