标准贯入试验击数与砂土参数间的统计关系

Statistic Relationship Between Standard Penetration Test Blow Count and Parameters of Sandy Soil

本文根据现场勘察资料及土工试验结果,分别建立了标贯击数与土的天然孔隙比、内摩擦角、压缩模量、剪切波速之间的关系式。利用这些关系式可根据标贯击数估算出砂土各参数。最后分析了各个关系式的误差及其产生的原因。

Based on the original investigation date and the result of soil test, the relationship equation between standard penetration test blow count and void ratio, inner fraction angel, compression modulus, shear wave speed of sandy soil is got respectively. By these equations, we can use the standard penetration test blow count to estimate the parameters of sandy soil. Finally we analysis the error of each equation and the causing of these error.
