本文简要叙述了宝珠寺水电站工程1987年设计复查的基本情况及成果,重点对设计复查中的几个主要问题进行了介绍和讨论:如大坝基岩抗剪断设计指标及建基高程的研究确定;利用导流明渠作为永久泄洪建筑物底流消能设施;取消进厂交通隧洞改为进厂公路;建议坝内引水钢管采取不留槽的施工方法;木材过坝设施的分期施工方案;天然砂石料改为人工砂石料;在原设计水头和转轮直径不变情况下,水轮机单机容量增加到17.5万kW的机组优化设计等。
This paper briefly describes the basic situation and results of the design review of Baozhusi Hydropower Project in 1987, and mainly introduces and discusses several major problems in the design review: for example, the research on the design indexes of the shear resistance of the foundation rock of the dam and the foundational elevation; The use of diversion channel as permanent inflow of energy-saving building inflow energy dissipation facilities; to cancel the traffic tunnel into the plant into the plant road; proposed water diversion pipe to take non-trough construction methods; timber dam facilities staged construction program; natural aggregate To artificial aggregate; in the original design of the head and runner diameter unchanged case, the turbine unit capacity increased to 175,000 kW unit optimization design.
