摘　　要：崖羊山水电站上游式大断面地下矩形调压室,断面尺寸43.5m×15m,总高达69m,采用纵、横向无支撑的薄壁结构,由围岩和一次支护为主承担山岩压力和内外水压力,并合理布置了排水系统,较好解决了围岩和结构结的稳定问题,在国内属首次应用,节省了工程投资,又加快了施工进度。The surge-chamber of the Yayangshan Hydropower Station is an underground and rectangular one with a large section on the upstream. The dimensions of the surge-chamber is 43.5m×15m×69m （L×W×h）. The thin-walled structures with no bearings in longitudinal and transverse directions is adopted in design. Roekmass pressure, and intend ＆ external water pressure are mainly acted on rockmass and initial supporting measures. In addltion, reasonable drainage system are arranged. As a result, the stability of structures and rockmass are successfully solved in this way. This new technology is applied firstly in China. So that it can save the project investment and accelerate the construction progress.
