300m级高土石坝反滤料制备技术研究OA
Study on the Process Technology of Filter Material for the 300 m-high Earth-rock Fill Dam
两河口水电站大坝为303 m高的砾石土心墙堆石坝,大坝反滤料Ⅰ和反滤料Ⅱ的设计要求与同类工程相比具有包络线范围较窄、制备难度大的特点.阐述了利用DGP1000B电子皮带秤对多种物料实施精确、快速、连续的掺配集中控制,并结合前期取得的经验教训,在瓦支沟反滤料系统中研究并采用了全湿法、两级反滤料掺配原料的方式,为大坝填筑提供了质量稳定、可控的反滤料,在施工现场通过精细化施工,保证了大坝高效、优质填筑,取得了提前387 d大坝填筑到顶的佳绩.
The Dam of Lianghekou Hydropower Project is a 303 m-high earth-rock fill dam with gravel-soil core.The design requirements for the dam's filter materials Ⅰ and Ⅱ have narrower envelopes and greater diffi-culty in preparation than similar projects.This paper describes the use of the electronic belt scale of DGP1000B to implement precise,rapid,and continuous centralized mixing control of multiple materials.Combined with the experience and lessons learned in th…查看全部>>
