摘要
骨料是混凝土的主要组成材料,骨料的品质对拱坝混凝土的技术性能及经济效益均产生重要影响。本文结合溪洛渡水电站及锦屏一级水电站的实际,对人工骨料的强度特性、耐久特性以及热力学特性等对拱坝混凝土性能的影响进行了试验研究,对两电站拱坝混凝土人工骨料的选择进行了分析和探讨。
Aggregates are concrete main component materials. The aggregates quality would proudce important influences on the arch dam concrete technical performances and economical benefit. In combination with practice of Xiluodu and Jinping I Hydropower Stations, in this paper the influences of the strength, durability and thermomechanical properties of the crushed aggregate on the arch dam concrete performances are tested and studied, and selection of the crushed aggregates for the arch dam concrete of the both hydropower stations are analysed and probed into.
