【 摘 要 】

In construction of mass concrete dams the main effect on the structure are temperature impacts. Heat release in cement hydration and the effect of many factors may result in considerable temperature gradients and cracks. The most dangerous here is the zone near the structure contact with the foundation bed. This manuscript gives analysis of dependence of the temperature regime and thermally stressed state of the zone near the structure contact with the foundation bed on the operating factors, preparation of recommendations on optimization of the construction procedure.
