| 中文摘要: |
| 通过实地监测了某医院直线加速器机房工程的大体积混凝土温度变化，简要分析了大体积混凝土温度应力裂缝的形成机理，阐述了控制混凝土内部温差的因素和具体实施措施，可有效的提高大体积混凝土结构的耐久性，并将控制方法应用到工程实例中。说明了控制措施的可行性和有效性，可为大体积混凝土施工中裂缝控制提供技术参考。 |
| 英文摘要: |
| Through monitoring of the temperature of large volume concrete changes a hospital linear accelerator room engineering, analysis of the formation mechanism of temperature stress crack in mass concrete, describing the factors of temperature difference control within the concrete and specific implementation measures. These measures can improve the durability of mass concrete structure effectively and also can be applied to the engineering example. These control measures have been proved to be feasible and effective, which can provide technical reference for crack control of large volume concrete construction expansion. |
