摘　　要： 以西北第一高楼-国瑞·西安金融中心为工程背景,设计了低水化热高流动性高强混凝土,选取1.7 m厚的钢板-混凝土组合剪力墙为足尺模型进行温度监测试验,对墙体混凝土的早期温度场变化规律、墙体内外温差变化规律以及墙表与环境温差变化规律进行了研究,并与规范进行了对比分析,为实际工程的后续施工提供依据,也为钢板-混凝土组合剪力墙的裂缝控制提供数据支撑和应对措施。 High strength concrete with low hydration heat and high liquidity was designed according to the engineering background of the highest building in northern China-Guorui-Xi＇an Financial Centre.A 1.7 metersthickness steel plate-concrete composite shearwall was chosen as a full scale model to conduct the temperature monitoring test.By the test, the early temperature evolution of the wall concrete, the temperature difference evolution inside and outside of the wall and the evolution between the wall surface and the environmental tempera- ture change were studied.The results based on the comparison and analysis between the test results and the code not only can provide refer- ences for the subsequent construction in practice but also offer data foundation and the corresponding measures to control the cracks of the steel plate-concrete composite wall.
