摘　　要：通过大量的试验研究,并在建立准确可靠的后装拔出法测强曲线的基础上,分析了粗骨料粒径、砂率、坍落度、掺合料掺量、混凝土龄期以及潮湿程度对测强曲线的影响,得出混凝土潮湿程度对测强曲线影响显著、其他因素影响均不明显的结论。from large number of examination study and based on accurate and reliable method of post bolt fixing pullout, analysis the affected Factors of Strength testing curve such as diameter of coarse aggregate, sand ratio, mixture ratio, concrete age and humidity. The conclusion gained that the affected factor of concrete humidity is notable but other factors.
