水平转体独塔单索面斜拉桥静载试验研究

绥芬河斜拉桥为独塔单索面、塔梁墩固结斜拉桥,采用水平转体施工,转体重量达14000 t,在国内尚属首创。介绍了绥芬河斜拉桥静载试验的主要内容和方法,通过对实测数据的分析整理,得出单个测点数值占各测点数值总值比例的方法进行各工况间比较,可以有效地减小环境因素对数值的影响;独塔单索面斜拉桥横向刚度大,偏载效应不明显;采用塔、梁、墩固结设计合理,施工质量优良,桥梁刚度和承载能力满足设计要求。研究结果可为同类型桥梁的设计和成桥试验提供参考。

Static Load Test and Research on Cable-Stayed Bridge with Horizontal Swivel, Single Tower and Single Cable Plane

The Suifenhe Cable-Stayed Bridge is a single tower,single cable plane and tower-beam-pier consolidation bidge which is constructed by horizontal swivel-construction,the weight amounts to 14 000tons which is originated in China.The main content and method of the Suifenhe Cable-Stayed Bridge static load test are introduced.And the method of proportion of single measuring point value to various measuring point value is obtained by analyzing the measured data and this method is carried on comparison among various loading condition.It can effectively reduce the influence of environmental factor on measured data.The lateral rigidity of cable-stayed bridge with a single tower and single cable plane is big and the effect of transverse eccentric loading is not obvious.Using tower-beam-pier consolidation,the bridge is designed reasonably and construction quality is fine,the bridge rigidity and the bearing capacity satisfy the design requirements.The research result can provide the reference to similar bridge design and bridge text.
