摘要
螺丝湾水电站引水隧洞洞线长，工程量大，施工条件困难，是控制发电工期的关键线路。技施中进行了优化修改，改圆形为方圆型洞，采用部分喷锚衬砌，增加一条施工支洞。
The power tunnel of the Luosiwan Hydropower Station was considered as a critical path in control of the commissioning date of the power plant due to its long length, large construction quantities and difficult construction conditions. Its design was optimized in the detailed design stage, i.e. its section was changed from the original circular shape to a revised horseshoe one; it is partially shotcrete and rockbolt lined, and one additional construction adit was arranged in the detailed design stage. As a result of this, the power plant was put into commissioning as scheduled.
