摘要
义乌市宗泽大桥主桥为三跨预应力混凝土V型墩连续刚构桥。为了检测桥梁结构的动力性能 ,对该桥进行了动载试验。采用四边型板单元的空间有限元方法对其进行动力有关分析 ,并与试验结果进行比较。结果表明 :该桥以竖向弯曲振动为主 ,且实测频率比理论值大。
Dynamic loading tests are made on Zongze Bridge, a three span prestressed concrete continuous rigid frame bridge with V shaped piers in Yiwu city, to find out the dynamic performance of bridge structure. After the dynamic analysis with space finite element method of quadrangle flat element and the comparing with test results, it shows that the bridge is mainly of vertical bending vibration and the practical frequency is more than that in theory, and the relation between the impact coefficient and vehicle driving speed is not obvious.
