青岛地区水运工程混凝土结构实体强度通用计算方法的研究与应用

Study on general calculation method for solid strength of concrete structure in Qingdao port and waterway engineering

通过测试6种不同强度等级,5个龄期的标准养护和自然养护混凝土试件,建立青岛地区水运工程回弹法和超声回弹综合法测强曲线,其精度满足规范要求。对6种不同强度等级,5个龄期的标准养护和自然养护混凝土试件进行钻取芯样,通过试验分析了芯样强度与混凝土抗压强度标准值的相关关系,建立了相关关系式,并应用到实际工程中进行验证。

Six kinds of different intensity levels,five instar standard conservation and nature conservation concrete specimens were tested to establish esting strength curve of Qingdao port and waterway engineering rebound method and ultrasonic-rebound.Its accuracy meets the specifications.Six kinds of different intensity levels,five instar standard conservation and nature conservation concrete specimens were drilled core samples.In order to establish a correlation type,the correlation between strength of core samples and the standard value strength of concrete compressive was analyzed by testing,and applied to the practical engineering for verification.
