摘要： 由于地基土的复杂性，及影响动力触探试验因素的多样性，使得不同地区的N120和N63.5击数的关系具有区域性，所以确定N120和N63.5的地区经验关系具有重要的意义，现结合工程实例讨论分析了动力触探试验N63.5和N120在德阳地区砂砾卵石层中的关系。

Abstract: Due to the complexity of the subsurface conditions in different areas and the factors that might potentially affect the blow counts in the Dynamic Cone Penetration Tests (DCPTs), it is proved that the correlation between blow counts obtained by different hammer weights, N120 and N63.5, are not unique. Soils in different areas might have different relationship. This paper discusses the relations between N120 and N63.5 in the sandy, gravelly and cobble soils in Deyang area.
