| 摘 要： | 基于波在无限体和一维杆中的传播理论，通过对标准立方体试块的超声、抗压强度试验和温柔凝土梁的超声、纵波波速试验进行对比，统计分析混凝土抗压强度、超声声速和纵波波速三者间的关系，进而将由纵波波速推算混凝土抗压强度用于工程实践。

| Abstract: | Based on the transmit theory of sound waves in infinite body and one dimension rod, the relationships among the concrete compressive strength, ultrasonic velocity and longitudinal wave velocity were analyzed through comparative test of the ultrasonic velocity and compressive strength of standard cubic specimen with the ultrasonic velocity and longitudinal wave velocity of concrete girder. And then the calculation of concrete compressive strength by longitudinal wave velocity was applied to practical engineering. |
