在水电工程建设中,从50年代起就提过在中小型水工建筑物和水电站建筑的构件方面存在着定型化和标准化的可能性;但实际上设计标准化的工作一直未能很好地开展起来,因而在某些方面造成了人力、物力和财力上的浪费。例如某省的三江口和遥田两水电站,先后于1976年底和1977年初由同一设计院提出初步设计报告。按照这一设计文件,两个电站的厂房均为 In the construction of hydropower projects, mention has been made since the 1950s of the possibility of finalizing and standardizing the construction of small and medium-sized hydraulic structures and hydropower stations; in fact, standardization of design has not been well developed In some respects, this has resulted in a waste of manpower, material resources and financial resources. For example, a province’s Sanjiangkou and the two hydropower stations in the ground, has in late 1976 and early 1977 by the same design institute to submit a preliminary design report. According to this design document, both plant sites are
