摘要
核心混凝土脱空对钢管混凝土构件力学性能的影响是当前研究的热点问题。针对营运6 a的西南某钢管混凝土拱桥拱肋核心混凝土的填充状况,通过相似模型试验和理论分析,浅述了脱空对钢管混凝土构件力学性能的影响,以期对钢管混凝土拱桥的设计、施工和检测提供一定的参考。
The research of the core concrete＇ s empty which influences the mechanics performance of concrete filled steel tube components is a hot issue currently. Aiming at the core concrete＇ s filled status of the concrete filled steel tube arch bridge which has been on operation for six years in southwest, through the similitude model trials and theoretic analysis, the core concrete＇ s empty influence on the mechanics performance of concrete filled steel tube components is briefly introduced. It offers referees to the design, construction and examination of this kind of bridge.
