摘　　要：设计了一种用于斜拉桥拉索风雨激振研究的试验装置 ,并进行了人工降雨雨振试验、人工水线雨振试验、气动措施制振试验及气动措施测力试验四组试验。试验结果表明 ,用此种试验方法研究拉索风雨激振是可行的 ,并得到了判断气动措施制振效果的定量分析方法。A test system was designed to study rain vibration of cables in cable-stayed bridge, and artificial rain wind tunnel test, artificial rivulet wind tunnel test, aerodynamic countermeasure to prevent rain vibration wind tunnel test and wind tunnel test to measure the wind force of aerodynamic countermeasure cable models were carried out. The results of test indicate that this method to investigate rain vibration is feasible, and a good way is acquired to quantificationally study the effect of aerodynamic countermeasures to mitigate rain vibration.
