浅议标准贯入试验指标的取值——兼与《地基基础设计规范》(GBJ7—89)编者商榷

On the Valuation of Index of Standard Penetration Test Consult the Editor of 《Design Code for Ground Foundation》(GBJ 7—89)

本文依据概率理论,推导出了标准贯入试验指标的取值公式,并分析了《地基基础设计规范》(GBJ7—89)中所采用的取值公式,指出了其不妥之处,旨在与其编者商榷。

Formula for computing the value of index of SPT is derived herein based on probability and the formula adopted in 《Design Code for Ground Foundation》is analyzed. The shortcomings of that formula are pointed out to be considered by the editor of the Code.
