摘要
根据两河口水电站的特点及泄洪要求,对泄洪建筑物的布置进行了研究。提出了4种布置方案,通过技术条件、施工条件等的综合分析比较,选定了深孔泄洪洞与洞式溢洪道相结合的布置方案,洞式溢洪道采用前隧洞、后明槽型式,深孔泄洪洞采用一坡到底无压洞型式,非常泄洪洞采用旋流竖井型式。调洪演算结果表明,该方案的总泄量达8300m3/s,可取得满意的泄洪效果。
Water-retaining building layout was studied according to characteristics and discharging requirements of Lianghekou hydropower station. Four layout schemes were proposed. The layout scheme of combining deep hole flood discharge cavity and cavity type flood discharge channel was selected after comprehensive analysis and comparison of technical conditions, construction conditions and the like. The cavity flood discharge channel adopts the form of tunnel in the front portion and trough in the rear portion. The deep hole flood discharge cavity adopts the form of integral slope without pressure cavity. The special flood discharge cavity adopts the form of vortex shaft. The flood adjustment calculation result showed that the total discharge quantity of the scheme can be up to 8300m3/s. Satisfied flood discharge effect can be obtained.
