两河口水电站心墙堆石坝防渗心墙料的研究

Research of Core Wall Rock-fill Dam Anti-seepage Core Wall Materials in Lianghekou Hydropower Station

两河口水电站工程堆石坝坝高295m,砾石土心墙料429万m3。由于该工程堆石坝高达300m级,国内尚无建设的成功经验,而且防渗土料分布较广,料源复杂。本文通过对防渗心墙的研究,论证了其合理性和可靠性,为同类型大坝心墙料的研究提供参考。

Rock fill dam of Lianghekou Hydropower Station Project is as high as 295 m.Gravel soil core wall material of 4.29 million m3 is adopted.Since the rock fill dam in the project reaches 300m grade,there is no successful construction experience in China.Besides,impervious soil materials are widely distributed,and material sources are complex.The reasonability and reliability of the core wall are discussed through studying anti seepage core wall,thereby providing reference for studying similar dam cor wall materials.
