Description
技术领域technical field

背景技术Background technique
在测量混凝土性能参数的实验中,常常需要测量混凝土的弹性模量,进而分析混凝土的缺陷分布。但目前的实验操作不科学,一是测量方式不严谨:目前用双手握着超声波探头,使其紧紧地贴在混凝土试样的两侧表面并使其对中,由于在两个超声波探头的中间隔了一个混凝土试样,这无法保证两个超声波探头同步运动及对中,而且也无法保证两个探头端面互相平行,导致测量的数据不准确;二是造成数据误判,由于操作方式带来的实验误差有时会使测量的数据超出预估值范围,但很难判断超出预估值范围的数据是操作不当造成的还是试样本身缺陷造成的,所以使得记录的数据不准确。In the experiment of measuring concrete performance parameters, it is often necessary to measure the elastic modulus of concrete, and then analyze the defect distribution of concrete. However, the current experimental operation is unscientific. First, the measurement method is not rigorous: at present, the ultrasonic probe is held with both hands, so that it is tightly attached to the two sides of the concrete sample and centered. There is a concrete sample in the middle, which cannot guarantee the synchronous movement and alignment of the two ultrasonic probes, and also cannot guarantee that the end faces of the two probes are parallel to each other, resulting in inaccurate measurement data; The experimental error sometimes causes the measured data to exceed the estimated value range, but it is difficult to judge whether the data beyond the estimated value range is caused by improper operation or the defect of the sample itself, which makes the recorded data inaccurate.
