Abstract：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 re‐lationship 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 sub‐w ay .
