Abstract

Abstract: A tube-concrete arch bridge in south-west china was removed due to its defects，sample were taken in arch ring and tested in laboratory， and strength distribution was found．In the light defect test findings，the modification of arch ring strength formula for tube-concrete bridge applying analytic theory of tube structure filled with concrete．

Key words: steel tube-concrete arch-bridge, defect, arch ring strength, formula modification

摘要： 鉴于西南某钢管砼拱桥存在较严重的安全隐患而拆除，对该桥的拱圈核心砼进行取样、试验研究，分析其强度分布规律．根据试验资料，讨论钢管砼拱桥应用现有的钢管砼构件理论进行计算时，其计算公式的修正．
