一、預冷骨料与水管冷却当大体积混凝土壩的高度增大,施工速度加快后,混凝土的散热措施逐渐成为高壩建筑中一个重要問題。预冷骨料与水管冷却,为目前解决混凝土散热两种常用的措施。为了减少散热量的来源,在大体积混礙土中,降 First, the pre-cooling aggregate and water pipe cooling When the height of the mass concrete dam increases, the construction speed, the concrete cooling measures have gradually become an important issue in the construction of high dam. Pre-cooling aggregate and water pipe cooling, cooling concrete for the current two common measures. In order to reduce the source of heat, in the mass of mixed soil, drop
