摘 要:
引入土层剖面随机场模型。把土性参数的点变异性和空间变异性联系起来。利用上海地区17个典型场地的直固快剪试验资料的统计结果。提出土层抗剪强度指标点变异系数的置信区间，建议在可靠度分析中使用置信上限估计值并考虑空间平均后的折减效应。[著者文摘]

Variability of Shear Strength Indices in Foundation of Soft Soil
Abstract:
By means of stochastic field model of soil profile, point variability and spatial variability of soil property parameters are associated in this article. Confidence intervals of point variability factors of shear strength indices in different soil layers are proposed based on statistical results of direct shear tests in 17 typical sites in Shanghai district. The upper bounds of confidence intervals are suggested to be used for reliability analysis and reduction after spatial average should be considered.[著者文摘]
