摘要
新时代下高铁客站建设以人为本,处处彰显温馨舒适.对中小型铁路站房1层候车厅空间进行优化,针对大跨度缓粘结预应力混凝土框架梁截面开孔及吊顶管线综合排布等难题,采用有限元分析试验验证,自主研制"一种扩大中小型高铁客站吊顶空间施工方法",通过预应力梁截面优化、BIM技术综合排布管线及抗震支吊架的应用,优化空间,并将地域文化元素与装饰装修设计深度融合,结合有吊顶与无吊顶形式,在保证工程施工质量及安全前提下,大大改善旅客候车空间,提升旅客舒适度.
Abstract
In the new era,the construction of high speed railway(HSR)passenger stations prioritizes a people-centric approach,ensuring warmth and comfort in every aspect.This study focuses on optimizing waiting hall spaces on the first floor of small and medium-sized railway station buildings.It aims to overcome challenges such as trepanning in the sections of large-span slow-bonded prestressed concrete frame beams and comprehensively arranging pipes on ceilings.A"construction method for expanding the space of suspended ceilings of small and medium-sized HSR passenger stations"was independently developed through finite element analysis and test verification.The space optimization involved improving prestressed beam sections,leveraging BIM technology for comprehensive pipe arrangement,and using seismic supports and hangers.Additionally,regional cultural elements were thoroughly integrated into the decoration design according to the situation with and without suspended ceilings.These enhancements significantly improved the waiting spaces for passengers,elevating comfort levels while ensuring construction quality and safety.
