摘要
根据循环三轴试验,分析了上海原状及重塑粉土的液化特性,提出了原状粉土的孔压上升模型,并与细砂的液化特性和孔丘模型进行了对比。
with cyclic triaxial tests, the liquefaction behavior of undisturbed silt and remoulded silt in Shanghai is analyzed. and the model of buildup of pore pressure of undisturbed silt is proposed in this paper. As compared, the liquefaction behavior and the model of pore pressure of fine sand are discussed.
