介绍了南昆线南盘江大桥大跨度Ｖ形支撑连续梁１／５０比例缩尺的有机玻璃模型试验结果。试验表明，该桥横向自振周期和水平挠跨比的试验值与采用ＳＡＰ程序的计算值符合良好，该桥的横向刚度满足要求。
The plexiglass model test results of the 1/50 scale of long span V - beam continuous beam of Nanpanjiang Bridge on Nanjian Line are introduced. The test results show that the experimental values of the period of horizontal self-oscillation and the ratio of horizontal deflection to span of the bridge are in good agreement with the calculated values by using the SAP program. The transverse stiffness of the bridge meets the requirements.
