摘　　要：结合欧洲黑山共和国南北高速公路Jabuka桥梁现浇梁施工实践,对比了欧洲特殊技术条款下的预应力张拉原理与国内预应力张拉原理,分析了预应力张拉设备与材料使用方面的不同之处,并对预应力张拉数据进行了分析。重点阐述了在欧洲标准体系下融入国内张拉理念的桥梁预应力施工的关键技术,期望能为同类工程提供有益借鉴。Combined with the practice of cast-in-place beam construction of the Jabuka Bridge on the North-South Highway Project in the Republic of Montenegro,in view of the importance of prestressed tensioning for bridge construction,comparisons on the prestressed tension principle are carried out under the European special technical provisions and the domestic prestressed tension principle,the difference between the prestressed tensioning device and the material is studied,and the prestressed tension data are analyzed.The key technologies of prestressing construction of bridges that integrated into the domestic tension concept are expounded under the European standard system which may provide useful reference for similar projects.
