EXPERIMENTAL INVESTIGATION ABOUT SOFT COHESIVE SOIL COEFFICIENT OF SECONDARY CONSOLIDATION IN BEIJING PLAIN

  • 摘要: 次固结系数通常被认为是一个常数,然而,大量的实验数据表明,随着时间的改变次固结系数也发生着变化。同样,大量的试验表明次固结系数与固结压力、压缩指数、含水率以及塑性指数有着一定的相关性。本文在着重研究北京平原区软弱黏性土次固结特性的基础上,对其规律进行了总结和分析。结果表明:对超固结土,次固结系数随荷载的增大而增大; 对正常固结土,次固结系数随荷载增大而减小。次固结系数亦随着土样含水率和塑性指数的增长呈线性增长趋势,且Cα/Cc比值为常数。
