由新日铁设计的宝钢焦化厂的钢筋混凝土水池,无论长度和宽度均超过我国规范规定的温度区段长度。水池除在使用期需承受水压以外,从施工期开始即承受由气温差、混凝土水化热降温差和混凝土干缩当量温差产生的温度应力。虽然就水池的体积和厚度来说,小于水工构筑物或某些地下构筑物等大体积混凝土结构,但是由于池底相当于现浇的连续板,池壁相当于现浇的连续长墙,又位于地面以上,受温度和湿度变化的影响极大,
The reinforced concrete pool of Baosteel Coking Plant designed by Nippon Steel Co., Ltd., regardless of its length and width, exceeds the length of the temperature section specified by the Chinese regulations. In addition to the water pressure applied during the service period, the pool is subjected to temperature stress from the beginning of the construction period, which is caused by the difference in temperature, the difference in temperature between the concrete’s hydration heat and the concrete’s dry shrinkage equivalent temperature difference. Although the volume and thickness of the pool is less than that of a massive concrete structure such as a hydraulic structure or some underground structures, because the pool bottom is equivalent to a cast-in-place continuous slab, the pool wall is equivalent to a cast-in-place continuous longwall and is located Above the ground, it is greatly affected by changes in temperature and humidity.
