大断面地下有轨电车装配式结构型式研究

Study on Assembled Structure Type of Large Section Underground Tram

地下交通结构断面大,采用装配式施工必然会存在大量接缝,极大的削弱了地下结构整体性与防水性能。研究总结了地下装配式结构设计型式,针对济阳有轨电车项目地下水丰富的特点,提出了上、下分块的设计型式,并建立了先整环拼装、后纵向拼装的大吨位的预制构件拼装方法,保障了拼装质量。

The section of underground traffic structure is large,and there will be a large number of joints when using assembly construction,which greatly weakens the integrity and waterproof performance of underground structure.The design type of underground fabricated structure is studied and summarized.According to the characteristics of abundant groundwater in Jiyang tram project,the design type of upper and lower blocks is proposed,and the assembly method of large tonnage prefabricated components with ring assembly first and then longitudinal assembly is established to ensure the assembly quality.
