摘要
利用常规直剪仪 ,对粉煤灰桩料———土进行了大量直剪试验 ,探讨了粉煤灰桩料———土接触面的强度特性 ,对接触面的应力应变关系作了讨论。得出了不同工况下粉煤灰桩料———土接触面上的Goodman单元之非线性参数 ,可供粉煤灰桩复合地基数值计算时参考。
Using direct shear apparatus, lots of pure shear tests have been done. Discussion on the ε-σ relation of the interface between flyash-lime pile and soil is given, in order to take a thorough inquiry into strain conditions. A none-linear nolinar parametre of Goodman elements in the interface was obtained, which supply reference for numberical calculation of composite foundation.
