Crest upstream side of the screen to build a certain height, can have water, wave function, can decrease again TianZhuLiang and panel of the area, reduce the construction cost. According to the concrete face rockfill dam design specification (SL228-98), the height of screen for 3.5 m. Researching crest above 1.0 m, elevation 158.0 m, The wall 154.5 m, wall bottom elevation higher than normal impoundment level 0.5 m, In order to facilitate inspection (walk, researching in upstream side floor height 154.9 m wide 0.8 m set of human pavement.
By researching the cantilever steel reinforced concrete structure, based on the design code for SL265 (gate - 2001), according to the method of researching on the retaining wall and anti-inclining stability against sliding and calculation, in controlling the load combination engineering cases and anti-inclining stability against sliding and meet the requirements specification.
Screen,
