摘　　要：华龙一号核岛预应力工程中水平预应力波纹管道安装质量影响着后期张拉摩擦阻力,而且影响准确建立设计规定的预加力值。同时其安装质量也影响着灌浆质量,进一步可能造成钢绞线的腐蚀,影响着安全壳结构的耐久性。通过对不同材质波纹管的适用情况、不同形式波纹管的力学性能以及表面处理工艺对摩擦系数的影响等方面进行对比分析,得出满足华龙一号水平预应力管道施工的波纹管以及核岛波纹管的性能参数。The installation quality of horizontal prestressed corrugated pipe in nuclear island pre-stressed project affects the later tension friction resistance,and affects the accurate establishment of the pre stressing value specified in the design.At the same time,the installation quality also affects the grouting quality,which may further cause the corrosion of the steel strand and affect the durability of the containment structure.In this study,through the comparative analysis of the applicability of different materials of bellows,the mechanical properties of different forms of bellows and the influence of surface treatment process on friction coefficient,the property parameters of corrugated pipe meeting horizontal prestressed pipe construction and the selection of nuclear island bellows are generated.
