针对采用超声法检测钢板厚度需打磨，而水利工程金属结构涂层破损后修复困难的情况，结合涂层厚度和超声法测钢板厚度的原理，研究了不破坏涂层的钢板厚度测量方法。重点从理论上对方法依据的原理开展了推导，并对方法的测量误差开展了分析，初步得到了误差的主导因素，同时依据理论研究，开展了3种类型构件共计300个测点的原型实验，并结合理论对实验成果进行了分析，得到了方法的主要控制因素。以上述成果为基础，充分考虑适用性和实用性，初步提出了无损涂层检测钢板厚度的方法，可作为水利工程钢板厚度检测的参考。

The steel plate thickness can be detected with ultrasonic method. With this method, the steel plate must be polished and it is difficult torepairpolishedmetalcoatinginwaterconservancyproject.Accordingtothecoatingthicknessandmechanismofultrasonicmethod,itresear-ches the measurement method of steelplate thicknesswith non-destructive coating.It derives the mechanism of method,and analyzes the meas-urement errors. Based on the above- mentioned method, the dominant factors of errors have been initially obtained. M eanwhile, according to the theory study, prototype test including three hundred measuring points for three types members has been done, and test results has been ana-lyzed. In addition, it also obtained main control factors. Based on the results, the method of coating non-destructive detection method for steel plate thickness has been primarily presented through fully considering suitability and practicability, which can provide references for detecting steel plate thickness in water conservancy project.
