[提要] 結(jié)合天津津濱輕軌車站結(jié)構(gòu)設(shè)計，介紹了城市輕軌高架車站結(jié)構(gòu)選型、荷載取值、荷載組合、結(jié)構(gòu)計算、構(gòu)件設(shè)計、基礎(chǔ)設(shè)計等方面的情況；比較了鐵路橋梁規(guī)范與一般建筑結(jié)構(gòu)設(shè)計規(guī)范在荷載組合、構(gòu)件設(shè)計等方面的區(qū)別；分析了溫度變化、基礎(chǔ)差異沉降對結(jié)構(gòu)內(nèi)力的影響；提出了相關(guān)的設(shè)計建議。
[關(guān)鍵詞] 城市輕軌 高架車站 站橋合一 荷載組合 樓板剛度溫度 差異沉降 樁基礎(chǔ)Combined with the structural design of elevated train station along Tianjin-Binhai mass transit project, the design problems about elevated train station are introduced, such as structure type, load value and load combination, structural analysis, member design and foundation design etc. The difference between the codes for the railway bridge design and for the ordinary building structural design in load combination, member design etc is compared. The effect of temperature change and foundation differential settlement on the structural internal force is analyzed. It gives some correlative design suggestions.
Keywords: station-bridge structure; loads; floor slab stiffness; temperature; differential settlement; pile foundation
