白水峪水电站引水发电系统的开挖支护设计和结构设计采取了一系列的优化设计。在引水隧洞、电站厂房和赤家峪改道隧洞的开挖支护上分别采用了：小进尺、多循环，加强跟班监测，锚杆支护，有取舍地进行灌浆等措施。压力钢管的岔管采用贴边岔型式。厂房采用新型“雁形板”屋面结构。通过近半年运行观察，证明了该优化设计是成功的，是个较好的范例。 Baishuanyu hydropower station diversion power generation system excavation support design and structural design to take a series of optimized design. In the diversion tunnel, power plant and Red River diversion tunnel excavation support were used: small footage, multi-cycle, to strengthen follow-up monitoring, bolt support, with choice of grouting and other measures. Pipe pressure pipe bifurcated side beam type. Plant using a new “geese” roof structure. Through nearly half a year of operation observation, it is proved that the optimal design is successful and is a good example.
