| 摘 要： | 温度裂缝是混凝土施工中常见的一种裂缝类型,也是土木工程界至今尚难于很好解决的工程实际问题之一.在南水北调中线京石段工程放水河渡槽施工中,采取了预防和控制温度裂缝的一系列综合措施,槽身混凝土在施工期未出现温度裂缝.实践证明,在大体积、高标号混凝土的施工及在外部环境温度变化较大地区混凝土的施工中,是可以采取综合温控措施来预防和控制混凝土温度裂缝产生的,或使结构尽可能不出现温度裂缝,或尽量减少裂缝的数量和宽度,从而确保工程质量. |

| Abstract: | The temperature crack is the common crack pattern in the concrete construction.On the river aqueduct construction of Fangshuihe River,the crack prevention and the temperature control measures have adopted.The results showed the trough body concretes without crack in the construction period.The practice proved that concrete construction in the great volume and the high-mark and the external environment temperature change area may prevent and control temperature crack. |
