摘　　要：大型地下电站引水洞压力钢管安装是一个复杂的施工问题,应充分考虑各环节的制约因素和前后环节之间的关系,综合研究质量、安全、进度、投资等各方面因素,使方案总体最优。根据国内已建和在建的大型地下电站工程资料,归纳总结了压力钢管几种主要的安装方案,并结合向家坝水电站的工程实例,论述不同施工方案的优缺点和适用条件,提出了有关建议。The installation of penstocks in large-sealed underground hydropower station is a eomplex eonstruetion problem. For obtaining a best installation program, the constraints of each process and the relationships between two processes must be eonsidered and various factors of progress, safety, quality and investment should be comprehensively researched when the installation program is formulated. Based on the data of a lot of large underground power stations in operation or under construction in China, the main programs of penstock installation are summarized. Combined with the construction of Xiangjiaba Hydropower Station project, the advantages and applicable conditions of these programs are discussed and some suggestions are also put forward.
