| 摘 要： | 针对实际工程中有时无法采用超声波对测法测量混凝土声速,而直接采用平测法所得声速计算混凝土强度时误差偏大的缺点,实验确定了平测法声速与对测法声速的比值,将修正后的平测法声速代入常规公式中即可准确得出混凝土材料的强度,解决了工程应用中的难题。

| Abstract: | It was difficult to measure the sound velocity by ultrasonic penetration testing in engineering sometimes, while the concrete strength determined with the velocity obtained by plane testing was not accurate. The velocity ratio of the two testing methods was given by experiment. The corrected velocity of plane testing could be used to determine concrete strength and the problem in engineering application was thus solved. |
