摘    要:大渡河泸定水电站3号泄洪洞消力池左右边墙设计为高27 m的直立边坡,由于两侧边坡存在较大地质缺陷,边坡稳定性较差,因此采取了直立边坡岩体的预固结灌浆及钢管灌注桩加固措施,以增加岩体的完整性并形成连续幕墙,从而确保了边坡安全并加快了工程建设进度.

关 键 词:消力池  直立边坡  管桩加固  泸定水电站

Abstract:The right and left side wall of stilling basin for the No.3 spillway tunnel in Luding Hydropower Station are designed as vertical slope with a height of 27 m.As the serious geological defects besides the stilling basin,the stability of slopes is poor.The rock mass surrounding the slopes are reinforced by taking pre-consolidation grouting and steel pipe piles to increase the integrity of rocks and form a continuous curtain wall.The safety of the slopes is guaranteed and the construction progress is speeded u...
Keywords:stilling basin  vertical slope  pipe pile reinforcement  Luding Hydropower Station
