摘　　要：根据氧化镁混凝土在不同温度下的膨胀性能,利用仿真分析方法,计算了掺氧化镁整体式常规混凝土拱坝在蓄水运行后的位移场,分析了氧化镁的延迟膨胀性质对不同季节坝体位移场的影响,为今后设计同类坝型提供参考.Based on the tested expensive properties of concrete mixed MgO under different temperatures, and by simulating the constructing processes of integral concrete arch dam, the displacement field of the dam in operation period is calculated. The expensive influence of MgO of different ratios on the maximum displacements at the dam crest is analyzed. The result may be severed as reference for designing a similar dam.
