摘要
目前,U形梁在国内轨道交通工程中已有较多应用,但尚未有成熟、系统的同心圆设计经验可供借鉴。结合南京地铁机场线工程,对高架U形梁段的同心圆设计进行详细阐述,从U梁施工工法角度,合理选取曲线加宽量,减少预制模具的种类,压缩模具及配套投入资金,利于"U"形梁规模化生产,也为以后类似工程提供参考。
At present,though widely used in many rail transit projects in China,there are not enough mature and systemic design experiences of concentric circles worth learning.In this paper,combined with Nanjing Airport Line,the concentric circle design of elevated U beam section is introduced in detail.From the angle of U beam construction method,the selection of reasonabe curve widening value,the reduction of prefabricated mould categories,compression mould and the matching funds,as well as the favorable condition for the scale production of U beam are discussed to provide a reference for similar projects in the future.
