摘要 对竖向固结系数的空间概率特征进行了统计研究 ,并进行了固结系数分布类型对固结度的敏感性分析。分析结果显示竖向固结系数的分布类型对固结度的概率计算有较大的影响。为便于工程设计应用 ,文后还提供了设计系数图表。 Features of spacial probability of vertical consolidation coefficient are studied herein.Sensitivity analysis of distribution pattern of consolidation coefficient to the degree of consolidation is also conducted.The results indicate the distribution pattern of vertical consolidation coefficient influence greatly on the probability calculation of degree of consolidation.For the use in engineering design a table of coefficients is attached to this paper.
