摘要
文中以守口堡水库胶凝砂砾石坝为例,针对胶凝砂砾石筑坝材料砂率随机分布及胶凝材料用量少的特点,研究了不同砂率及不同水泥用量对胶凝砂砾石试件抗压强度的影响。结果表明:胶凝砂砾石试件的抗压强度随着砂率的增加先增大后减小,随着水泥用量的增加而增大。试验推荐胶凝砂砾石筑坝材料的砂率为30%,水泥用量为50 kg/m^3。
Taking the cement-sand-gravel dam of Shoukoubao Reservoir as an example,aiming at the random distribution of sand rate of cemented gravel dam materials and the characteristics of less cementitious materials,the influence of different sand rate and different cement dosage on the compressive strength of cemented gravel specimens is studied. The results show that the compressive strength of cemented gravel specimens increases first and then decreases with the increase of sand content,and increases with the increase of cement content. It is recommended that the sand ratio of cemented gravel dam material is 30% and the cement dosage is 50 kg/m^3.
