本文叙述新丰江坝原型振动试验的方法和主要结果。用多台起振机进行稳态强迫振动试验,测定了该坝前十阶自振频率、阻尼和振型。文中还对不同激振位置的效果进行了比较,对坝体变形特性进行了探讨。 This paper describes the method and main results of prototype vibration test of Xinfeng River dam. The steady state forced vibration test was carried out by using a plurality of starting machines, and the natural frequency, damping and vibration mode of the ten order before the dam were measured. The article also compares the effect of different excitation positions, and discusses the deformation characteristics of the dam.
