标贯试验在膨胀土承载力分析中的应用研究

Applicable Research of Standard Penetration Testing Bearing Capacity in Expansive Soil

基于邢台市区膨胀土的主要性质,采用标准贯入试验进行了膨胀土承载力分析,并基于数据回归分析和工程经验,归结出了膨胀土承载力分析方法的适用范围。实践证明,在膨胀土承载力分析过程中,由于采用了将试验击数与载荷试验直接对比进行回归分析,具有相当的准确性和科学性。

Based on main characteristics of expansive soil in Xingtai city,the author analyzes bearing strength of bearing soil in the standard penetration tests.According to data regression analysis and engineering experiment,this essay concludes the applicable scope of analysis method of bearing capacity in expansive soil.It is reported that the methodology is of accuracy and science by using of regression analysis compared experimental knocking times with loading experiment in analyzing bearing capacity in expansive soil.
