摘要
本文针对现行《公路钢筋混凝土及预应力混凝土桥涵设计规范》( JTJ0 2 3— 85)、《公路砖石混凝土桥涵设计规范》( JTJ0 2 2— 85)中混凝土抗压强度采用标号表达 ,《公路工程质量检验评定标准》采用混凝土强度等级表达。
This paper is directed against different expressive way of concrete strength,Such as the concrete strength of current《Design Standard of Bridge and Culvert in Reinforced Concrete and Prestressed Concrete of Highway》(JTJ023? ?5)and《Design Standard of Bridge and Culvert in Brick and Stone Concrete of Highway》(JTJ022—85)adopts grade to exp ress,《Standard of Quality Test and Evaluation of Highway Engineering》adopts Strength class to express.The author disc usses adopting different standard leading to the confusion of concrete quality control in the design and construction.
