摘要: 為了解決城市廊道資源的緊張和公共交通發(fā)展需求的矛盾,出現(xiàn)了軌道交通和快速路的共建型式,即公軌共建的復(fù)合型交通模式,以溫州市域鐵路 S2 線一期工程的人民路站為例,研究公軌共建高架車站的結(jié)構(gòu)設(shè)計要點。 首先,為降低淺層氣體對樁基的承載力及沉降影響,對遇到局部淺層氣體發(fā)育的基礎(chǔ)設(shè)計提供了合理的解決方案。 然后針對公軌共建一體化車站分別進行了多遇和罕遇地震作用分析,研究表明構(gòu)件及整體指標(biāo)滿足規(guī)范要求。 最后針對工程的一些關(guān)鍵技術(shù),如快速路橋面體系的選型、超長結(jié)構(gòu)溫度應(yīng)力的控制措施、軌道梁撓度及應(yīng)力的控制、快速路橋面振動對車站的影響等進行了分析,并給出了具體的解決方案和指導(dǎo)意見。

Abstract: In order to solve the contradiction between shortage of urban corridor resources and development needs of publictransportation, that is a composite transportation mode constructed by public rail. Taking the Renmin Road Station on theS2 Line of Wenzhou Municipal Railway as an example, the main points of the structural design of the public railco ̄construction station were studied. First of all, in order to reduce the impact of shallow gas on the bearing capacity andsettlement of the pile foundation, a reasonable solution for the foundation design that encounters local shallow gasdevelopment was provided. Then, an analysis of the effects of frequent and rare earthquakes was carried out for the publicand rail co ̄construction integrated stations, and the research showed that the components and the overall indicators meet therequirements of the code. Finally, some technologies of the project were analyzed, such as the selection of the expresswaybridge deck system, the control measures for the temperature stress of the super ̄long structure, the deflection and stresscontrol of the track beam, the influence of the expressway bridge deck vibration on the station, etc. Specific solutions andguidance were given.
Keywords: public rail co ̄construction elevated station;shallow gas;integration of bridge construction;pier topdisplacement;track beam;temperature stress
