亭子口水利枢纽工程设计

Design of Tingzikou Water Control Project

亭子口水利枢纽工程为一等大(1)型水利水电工程,永久主要建筑物为1级,电站厂房为2级,下游护岸工程等建筑物为3级。表孔及底孔泄水建筑物布置在河床中间,底孔兼作三期导流底孔,左岸布置坝后式厂房,右岸布置垂直升船机。工程为红层地区最高的重力坝,坝基存在缓倾角软弱夹层,大坝深层抗滑稳定等是该工程设计的关键技术问题。

Tingzikou Project is a Class I and First-large type water resources and hydropower project, the main permanent buildings belongs to Type 1, the powerhouse belongs to Type 2, and downstream bank protection works belongs to Type 3. Upper outlet and bottom outlet are deployed in the middle of the riverbed. Bottom outlet is also being as the discharge structure of third period diversion. The power plant is located on left bank of darn, the vertical ship lift is in the right bank of dam. The gravity dam is highest in red layer region. There is low-angle weak interlayer in dam foundation, and the dam stability against deep sliding is the key issues of the engineering design.
