摘　　要：针对兰州地铁结构混凝土强度质量控制问题,将不同配合比兰州地铁混凝土试件标准养护至一定龄期,并根据检测出的混凝土抗压强度和超声声速的实验结果,建立混凝土抗压强度与超声声速之间的相关关系.结合国外规范及国内学者的研究成果,将该相关函数关系与其它关系式作对比分析,可为无损检测混凝土强度及兰州地铁工程的耐久性评估提供理论依据.Aiming at the problem of concrete strength control in Lanzhou subway,concrete specimens with different mixture ratio were tested after standard curing condition.According to the test result,the relationship between compressive strength for concrete and ultrasonic velocity were established.In addition,combined with foreign standards and domestic scholars＇ research results,a comparative analysis of the functional relationship between this paper and the others was performed,which provides the theoretical basis for the durability evaluation and nondestructive test of concrete compressive strength in Lanzhou subway.
