我国钢结构工程多使用摩擦型高强度螺栓进行连接，该种连接方式能够使螺杆与螺母之间产生巨大的预紧力以及接触面，继而提高构建之间的摩擦力，高强度螺栓预紧力是难以在施工过程中进行测量的，必须要通过螺栓扭矩进行控制，而不同螺栓纹面摩擦因数具有离散性的特征，这就会导致轴向应力离散，将超声测量技术应用在钢结构工程中高强度螺栓轴向应力中的测量能够有效的减小由于人工测量产生的误差，可以实现在线检测、无损检测，本文主要分析超声测量技术在钢结构工程中高强度螺栓轴向应力中的测量方式。

China's steel structure engineering using the connection of friction type high strength bolt, the connecting mode can make between the screw and the nut produce pretightening force huge and contact surface, and then improve the friction between the construction, high strength bolt pretightening force is dif icult to measure in the construction proces , we must control ed by bolt torque, and dif erent bolt surface friction factor is discrete features, this wil cause the axial stres of discrete, the application of measuring ultrasound technology in the steel structure engineering in high strength bolt axial stres measurements in can ef ectively reduce the artificial measuring er or generated, can realize online detection, nondestructive detection this paper mainly analysis, measurement of ultrasonic measurement of high strength bolt axial stres in the steel structure project.
