摘　　要：堆石坝各区填筑所需开采料级配存在差异,料场爆破是高效获取坝体填筑料的重要方式,为满足坝体分区填筑需求,开展料场爆破试验以明确爆破参数与开采料级配之间的关联关系是确保快速优质填筑施工的关键。文章依托高海拔区玛尔挡堆石坝坝体填筑工程,匹配坝体分区填筑需求,开展了二长岩料场分层开挖过程的爆破实验,对已获得的爆破参数进行优化。研究结果表明:使用优化后的爆破参数可满足设计级配的堆石料,为同类型工程料源爆破试验的开展提供了借鉴。There are differences in the gradation of mining materials required for the filling of rockfill dams in different zones.The blasting of the material yard is an important way to obtain the filling materials of the dam body efficiently.In order to meet the needs of the filling of the dam body,the blasting test of the material yard is carried out to clarify the relationship between the blasting parameters and the gradation of the mining materials.It is the key to ensure the rapid and high-quality filling construction.Based on the filling project of Maerdang rockfill dam in high altitude area,the blasting experiment of layered excavation process of adamellite yard was carried out to optimize the obtained blasting parameters.The results show that the optimized blasting parameters can meet the design gradation of rockfill materials,which provides a reference for the development of the same type of engineering material source blasting test.
