上海典型软土基本物理力学指标分析
|
摘要
基于大量上海土的试验资料,总结了上海不同地点的淤泥质黏土的基本物理力学指标,对其进行统计分析给出了位置特征指标数、离散性特征指标和分布特征指标等统计指标,以及指标间的相关关系,并得出了物理力学指标间相关系数绝对值大于0.5的经验公式。这些工作对以后的工程实践和数值模拟具有指导性意义和参考价值。
Based on a large number of test results of Shanghai soft clay,basic physical properties and indexes of muddy clay from different locations in Shanghai were summarized. Then,statistical analysis was presented on the statistic index such as location feature index,dispersion characteristics and distribution characteristics and their correlations were carried out and the correlation coefficient between physical indexes of absolute values greater than 0. 5 empirical formulas. These work would guide significance and reference value for the future engineering practice and numerical simulation.
