大体积混凝土坝在施工过程中,采取合理的控制温度防止裂缝的标准和措施是关系到工程质量和进度的重大问题之一。要解决好这个问题,必须制定一个合理的温控标准及其防裂措施。在制定这些标准和措施中需要进行大量的温度计算工作,为此掌握一个正确而简捷的温度计算方法是十分必要的。混凝土浇筑块的初期温度计算是一个比较复杂的问题,这是因为内部有水化热温升,同时要考虑浇筑块顶面散热、底部老混凝土(或基岩)传热、浇筑块内部埋设的水管通水冷却等
In the process of construction, it is one of the major issues that affect the quality and progress of the project that the mass concrete dam should take reasonable measures to control the temperature and prevent cracks. To solve this problem, we must formulate a reasonable temperature control standard and crack prevention measures. In the development of these standards and measures need a lot of temperature calculation work, to grasp a correct and simple temperature calculation method is very necessary. The initial calculation of concrete pouring block temperature is a more complicated issue because of the internal heat of hydration, taking into account the top of the pouring block heat, the bottom of the old concrete (or bedrock) heat transfer, embedded within the pouring block of water pipes Water cooling and so on
