In accordance with the expression of the correction of rod length to the blow counts of standard penetration test (SPT) in the "Code of Geotechnical Investigation" (GB 50021-94) ;in this paper, the author poses his viewpoint of the correction of rod length for the value of blow counts during conducting SPT is necessary.

本文根据《岩土工程勘察规范》(GB50021—94)关于标准贯入试验锤击数(下称标贯击数)杆长校正问题的表述,对标贯锤击数是否应作杆长校正提出了作者的看法,认为在目前情况下,对标贯击数值进行杆长校正是必要的。
