摘要
介绍了吉林松原斜拉桥静动载试验的主要内容和方法,并结合理论计算,对该桥梁结构的实测应力、挠度及振动特性进行了对比分析。实验结果表明,该桥理论分析和设计计算方法可靠,施工质量优良,桥梁刚度和承载能力满足设计要求。
The paper introduces major contents and methods for test of static and live loads on Jilinsonyuan cable - stayed bridge and analyzes by contrast the mearured stress of present bridge structure, its deflection and vibrating characteristics in the light of theoretical calculation. Experimental results demontrate that the theoretical analysis of present bridge and design computing methods are reliable, the construction quality is fine, the rigidity and bearing capacity of bridge satisfy requirements for design.
