Anti-seepage Design of Rockfill Concrete Gravity Dam Body
In order to ensure the reliability and safety of anti-seepage design of rock-fill concrete gravity dam,the use of 0.5 m thick W10 anti-seepage self-compacting concrete and 2.0 m thick anti-seepage rock-fill concrete are firstly proposed to form a dam anti-seepage system.The design anti-seepage grade and design thickness of dam anti-seepage layer material can meet the requirements of current code by calculating hydraulic gradient and pressure head.The technical requirements of horizontal construction joint of impervious layer are put forward.
