摘　　要：西十高铁漫川关车站站场规模2台5线,设岛式站台2座,到发线有效长650 m,车站大小里程侧设置在桥梁上,车站中部设在路基上,桥墩高度范围6~66 m,车站横向宽度12.6~47.0 m,横向地形呈单向坡,地形条件复杂,是非常典型的山区高速铁路车站桥梁。以漫川关车站桥为例,阐述高速铁路山区车站桥梁的设计难点、设计原则、控制因素,探讨车站桥梁的总体布置,比选分析车站桥桥墩、站台梁、轨道梁的结构形式,确定桥梁采用箱梁梁部、多柱墩桥墩形式,为高速铁路山区车站桥梁设计提供借鉴。The Manchuanguan Station on the Xi’an-Shiyan HSR features a station layout consisting of 2 platforms and 5 tracks,with 2 island platforms.The effective length of the receiving-departure track is 650 m.The station’s large and small mileages are set on a bridge,while the central part of the station is situated on the subgrade.The height of the piers ranges from 6 m to 66 m and the lateral width of the station varies between 12.6 m to 47 m.The lateral terrain presents a one-way slope,and the terrain conditions are complex,making it a very typical mountainous high speed railway station bridge.Taking Manchuanguan Station Bridge as an example,this study outlines the design challenges,principles,and control factors associated with high speed railway station bridges in mountainous areas and explores the overall layout of the station bridge and conducts a comparative analysis of the structural forms of bridge piers,platform beams,and track beams.The findings confirm the selection of box girder structures and multi-column pier forms for the bridge,providing valuable references for the design of HSR station bridges in mountainous areas.
