Abstract在3种不同围压下进行了一系列重塑粉质黏土的静三轴和动-静三轴不排水剪切试验,得到了不同动应力水平条件下粉质黏土的孔压、动应变和不排水剪切强度值.通过对土样的不排水强度、孔压和动应变的无量纲化处理,确定了周期荷载作用后粉质黏土的不排水强度比与动载引起的孔压比和动应变比之间的相关关系.试验结果表明:粉质黏土在周期荷载作用后的不排水强度衰减程度取决于动载引起的动应变比值和孔压比值.当周期荷载引起的动应变比值小于0.1时,孔压比增长较快,土样的不排水强度几乎没有衰减;当动应变比大于0.1时,孔压比增长变慢,土样的不排水强度明显衰减;当动应变比值接近1时,孔压比值达到0.9,土样的不排水强度衰减程度约达到55 %.
