Analysis of Variability and Correlation of Shear Strength Indexes Typical Stratum in Beijing Area

BGI Engineering Consultants Ltd., Beijing 100038, China

摘要: 新近沉积层是北京地区典型的浅部相对软弱土层,土层力学指标变异性较大。依据北京地区大量实际工程的勘察资料,采用土层分布随机场模型,对北京地区新近沉积典型地层的抗剪强度指标的空间概率特征进行统计分析,北京地区新近沉积土层的自相关距离一般为3~4 m,是比较合适的取样间距。

Abstract: The recently deposited stratum is a typical shallow and relatively weak layer of the main soil layer involved in project construction in Beijing area. The variation of soil mechanics index is great. Based on a large number of practical engineering in Beijing area, shear strength variability and spatial variability of soil property parameters are associated by means of stochastic field model of soil profile. Variation laws of the correlative distance and spatial variability coefficient are gained by statistic analysis of shear strength indexes of recently deposited typical stratum. The autocorrelation distance of newly deposited soil layers of Beijing area is generally 3~4 m, which is a suitable sampling interval.
