摘　　要：为保证阿尔塔什面板堆石坝砂砾石冬季填筑施工,结合大坝砂砾石料碾压试验进行了冬季施工不加水薄层碾压试验,以确定砂砾石料冬季施工填筑碾压最优控制参数。砂砾石料冬季施工技术关键应抓好料源质量控制,采取薄铺干碾、松铺保温。阿尔塔什大坝砂砾石料冬季施工技术成功实践应用,保证了冬季填筑施工质量和工程度汛安全。In order to ensure filling construction quality of sand and gravel material in Aertashi CFRD in winter, the thin-layer rolling tests without water adding of sand and gravel material in winter for the construction dam are carried out for determining the optimal control parameters of sand and gravel material rolling. The key technologies of sand and gravel material construction in winter include the quality control of material source and the applications of thin-layer spreading and dry rolling and insulation with loose spreading layer. The successful application of winter construction technologies of sand and gravel material in Aertashi Dam ensures the winter construction quality and the engineering safety in flood season.
