摘要
通过标准砂与三种粉煤灰在不同密度、不同固结应力下的三轴加载-卸载-再加载试验,着重探讨了粉煤灰的颗粒破碎、剪胀及普遍反向剪缩特性。在此基础上对建立粉煤灰单调及循环荷载下的液化分析模型提出了建议。
Based on a comparison of a series of test results for sand and coal ash under different densities and confining pressures, several main properties of coal ash are discussed, i. e. particle breakage, dilatation and inversion compression. Finally, some suggestions are made for liquefaction analysis of coal ash.
