一、概述随着筑坝技术的发展,土石坝心墙土料的选择范围日趋广泛。冰碛土、风化岩、砾质土都可作为心墙材料。经过必要的物理力学性质试验,采用专门的开采、筛选、拌和等措施,并保证土料颗粒级配良好、拌和均匀和碾压密 First, an overview With the development of damming technology, Earth-rock dam core materials increasingly wide range of choices. Moraine soil, weathering rock, gravel soil can be used as the core wall material. After the necessary physical and mechanical properties of the test, the use of special mining, screening, mixing and other measures, and to ensure that the particle size grading well, mixing and rolling compacted
