摘　　要：压力管道过缝结构型式对坝后式水电站结构的安全性和实用性影响较大,大型水电站以采用波纹管伸缩节,或取消伸缩节而采用其它有效的替代结构为发展趋势.从工程实践和研究进展两个方面,全面介绍了水电站压力管道取消常规伸缩节的近期成果,并展望了需进一步研究的一些问题.The security and practicability of hydraulic structures are influenced by pipe structure for passing joints markedly. The research advance shows that expansion joints bellows will be used or expansion joints will be cancelled in large hydropower stations. Based on engineering practice and advance of research, the current achievements about canceling expansion joints are reviewed. Some research subjects in future are presented.
