摘要
标准贯入击数N值的修正是一个复杂急待解决的问题。在推荐以N=N’×(1一l/200)公式进行杆长能量传递修正后,进而推荐以弯曲修正系数λ进行N值的二次杆长修正。并根据华东沿海地区大量实测数据回归统计,得到地区性λ值表。
The correction of SPT blow count is a complex problem impending for solution. We recommend the formula N=N'(1—1/200) for energy transfer correction of rod length. Then, we recommend a curvature correction coefficient λ for secondary rod length correction of SPT blow count N63.5. Based on the retrogressive statistics of a large amount of data measured at the China east coastarea, a table of regional λ value is obtained.
