摘　　要：对混凝土表层潮湿与饱水的射钉试验分析表明,表层潮湿的混凝土对射钉外露长度有影响,强度越低影响越显著;混凝土饱水对射钉外露长度的影响高度显著,并提出了混凝土饱水时射钉外露长度的修正值。The pin penetration tests on concrete with wet surface layer and saturation concrete were conducted. The results indicate that concrete with wet surface layer has an effect on outcrop length of pin and the effect is notable for low strength concrete, saturation concrete has an more prominent influence on outcrop length. An value is proposed to modify the outcrop length of pin for saturation concrete.
