风积黄土地层标贯试验确定承载力回归公式初探

国内外关于标准贯入试验与砂土、黏性土承载力关系的回归公式比较多,然而,对于第四系上更新统风积的湿陷性黄土承载力与标准贯入试验锤击数的关系的研究相对较少。通过大量试验数据推导出一个适合第四系上更新统风积新黄土的回归公式,并通过实例进行验证,可为今后同类地区该土层承载力的估算提供一种参考。

Study on the Regression Formula for Standard Penetration Test and Bearing Capacity in Eolian Loess Layers

There are many researches on the regression formula for standard penetration test and bearing capacity. However, the study on the relationship between the collapsibility loess of Upper Pleistocene of Quaternary and the standard penetration test blow count are relatively scarce. Based on a large number of experimental data, the paper deduces a regression formula which suits the loess of Upper Pleistocene of Quaternary, and is verified by practical examples, which can provide a reference for the estimation of future similar regions of the soil bearing capacity.
