空心薄壁墩施工关键技术的控制空心薄壁墩施工关键技术的控制 中图分类号:TU7 文献标识码:A 文章编号: 摘要:铁路工程高墩设计多采纳双线圆端形空心墩,因为它可以提供很大的横向刚度,并且在常常承受列车荷载时竖向刚度比单线桥增加一倍,还有外形美观、自重轻等优点
但是空心墩的施工难度也较大,施工质量难控制,本文介绍对空心墩的施工中关键技术的控制

But the hollow of the pier construction difficulty also bigger, construction quality difficult to control, this paper introduces the construction of hollow piers of the key technology of control
Keywords: hollow thin wall pilla; The key technology; control 随着铁路建设事业的进展,客运专线里程迅速增长,客运专线桥梁从结构上要求刚度大、整体性好,工程设计多采纳双线圆端形空心墩,因为它可以提
