大朝山水电站尾水系统采用长尾水隧洞，需设置尾水调压室。经可研、初设、招标、技施设计，对于尾调的形式、水力稳定面积、阻抗孔口尺寸和体形、水力过渡形态、横向水流和立轴漩涡、疏流墩、最高最低涌浪水位及确定的尾水调压室总体高度、洞室衬砌形式、洞室围岩稳定、围岩开挖和支护、结构分析诸问题，逐步深入分析、随设计阶段进展、施工的进程，不断根据新出现的问题，跟踪进行修改、优化，做了有益的探索。
The Dachaoshan Hydropower Station tailrace system uses a long tailrace tunnel and a tailrace surge tank is required. After the feasibility study, preliminary design, bidding, technical design, the form of tail adjustment, hydraulic stability area, impedance orifice size and shape, hydraulic transitional form, horizontal flow and vertical swirl, dredging pier, Determine the overall height of the tailrace surge chamber, tunnel lining form, the stability of the surrounding rock cavity, surrounding rock excavation and support, structural analysis of the problems, and gradually in-depth analysis, with the design stage, the construction process, and constantly according to the new Problems that arise, tracking changes, optimization, do a useful exploration.
