The invention belongs to the technical field of prestressed structure detection, and particularly relates to a prestressed structure detection device and method based on a piezoelectric fluctuation method. Corresponding stress wave drivers and stress wave sensors are arranged on polygonal nuts and base plates of a prestressed structure, the stress wave drivers send stress waves, the stress waves are transmitted in the prestressed structure, and then feedback signals are received through the stress wave sensors. And calculating and analyzing to obtain the prestress loss condition in the prestress structure. According to the detection structure and method disclosed by the invention, the prestress loss condition in the prestress structure can be quickly and accurately obtained, so that the internal prestress of the prestress structure can be kept in a reasonable range, and prestress failure is avoided. 本发明属于预应力结构检测技术领域，具体涉及一种基于压电波动法的预应力结构检测装置及检测方法。本发明通过在预应力结构的多角螺母和垫板上设置对应的应力波驱动器和应力波传感器，应力波驱动器发送应力波，应力波在预应力结构内部传递，
