 [摘要] 天津西站北廣場(chǎng)地下工程為超長(zhǎng)半地下結(jié)構(gòu)，設(shè)計(jì)中同時(shí)面臨了地鐵區(qū)間段下穿形成的大跨結(jié)構(gòu)，以及結(jié)構(gòu)凈高的嚴(yán)格控制。通過采用短向受力框架體系、溫度效應(yīng)分析、預(yù)應(yīng)力設(shè)計(jì)等手段，綜合解決了上述設(shè)計(jì)問題，相關(guān)方法與思路可為同類型結(jié)構(gòu)設(shè)計(jì)提供參考。

Abstract: North square of Tianjin west railway station underground structure is a semi-underground structure, of which the long span structure over metro section and the clear space should be considered in design. Design difficulties were successfully solved by adopting short-direction-supported frame system, temperature effect analysis, prestressed concrete design method. The design methods adopted in this project can provide reference for the similar structure design.

Keywords: super long; underground structure; structural arrangement; temperature effect; prestressed
