Abstract

The hydration heat of cement always causes large temperature difference between surface and core area of mass concrete at early ages due to its huge volume, which is apt to cause concrete to crack. Cooling water pipes are often installed to carry out part of the mass concrete internal heat, therefore the cracks can be avoided. Based on a railway bridge mass concrete pile caps construction, three key parameters of cooling pipes, which are pipes spacing and flow rate of cooling water as well as pipeline layout are studied by Midas/Civil software in this paper, and an optimized cooling pipes design is proposed.
