(76+3×120+76)m连续梁是杭甬客运专线最长的连续梁,也是本线的重点工程。从箱梁的构造特点、内力分析、预应力体系以及动力分析成果等方面介绍了该连续梁设计,可为客运专线铁路同类桥梁结构提供有益的参考。
(76+3×120+76)m連續樑是杭甬客運專線最長的連續樑,也是本線的重點工程。從箱樑的構造特點、內力分析、預應力體繫以及動力分析成果等方麵介紹瞭該連續樑設計,可為客運專線鐵路同類橋樑結構提供有益的參攷。
(76+3×120+76)m련속량시항용객운전선최장적련속량,야시본선적중점공정。종상량적구조특점、내력분석、예응력체계이급동력분석성과등방면개소료해련속량설계,가위객운전선철로동류교량결구제공유익적삼고。
(76+3×120+76)m continuous girder is the longest continuous girder on Hangzhou-Ningbo Passenger Dedicated Railway,and is also a key project on the line.The paper introduces the design of continuous girder structural from box structural formation features,internal force analysis,prestressing,dynamic analysis and so on.The presentations in the paper provide helpful reference for the design of similar bridges for passenger dedicated railway.
