水泊渡水库面板堆石坝现场碾压试验及分析

Analyses & Rolling Test in Site for Face Rockfill Dam of Shuibodu Reservoir

为确保水泊渡水库面板堆石的填筑质量,施工前进行了7种填筑材的现场碾压试验,证实坝体分区及筑坝材料级配曲线的设计是合适的。同时,通过现场碾压试验确定的大坝填筑碾压设备及与之相匹配的碾压参数,亦能够满足大坝填筑的质量要求。

In order to guarantee building quality of face rockfill dam,seven filling materials were tested in site rolling before constructing,the results verified the design of dam body sub-zone and filling material grade curve was suitable.Meanwhile,dam filling and rolling equipment and matching rolling parameters defined through rolling tests in site can meet the quality requirement of dam filling.
