为了探讨粗集料灌入试验的合理参数取值,利用UTM-100测定了成型方式、容量筒规格、压头直径和贯入速度等因素对粗集料灌入曲线的影响。结果表明:成型方式采用干捣实法、容量筒规格采用15L、压头直径采用100~120 mm、贯入速度小于7.5 mm/min时,贯入试验可达到较好的效果。 In order to investigate the reasonable parameters of the coarse aggregate pouring test, the influence of the forming method, the size of the cylinder, the diameter of the indenter and the penetration velocity on the pouring curve of the coarse aggregate was determined by UTM-100. The results show that the molding method adopts dry tamping method, the capacity of the cylinder is 15L, the diameter of the tampon is 100-120 mm, and the penetration speed is less than 7.5 mm / min, the penetration test can achieve better results.
