摘要
鉴于自锚式斜拉-悬索协作体系桥结构新颖,目前世界上尚无先例,为了检验其设计及计算理论的正确性,探索自锚式斜拉-悬索协作体系桥的整体结构特性,以大连湾跨海大桥推荐方案为原型,制作1/100的试验模型,进行全桥静力和动力模型试验分析,试验结果与理论结果基本吻合.试验验证了理论计算的正确性,表明用现有的有限位移理论分析是安全可靠的.为实际工程的设计与力学性能研究提供依据.
The self-anchored cable-stayed suspension bridge is a new type bridge structure. In order to check the design of structure and study on the structure characteristics,a model of Dalian Gulf Bridge is made, which similarity scale is 1/100. The results of the experiments are consistent with those of theoretical analysis. The static force performance of self-anchored cable-stayed suspension bridge can be analyzed by finite displacement theory. The conclusions can offer the helpful basis for research and design on self-anchored cable-stayed suspension.
