ABSTRACT
Gravity dams are structures whose stability under the influence of all forces and effects is ensured mainly by their weight. Reliability of concrete gravity dams is based first of all on the high compressive strength of the concrete; due to the limited tensile strength of concrete, gravity dams are designed in such a way as to exclude tensile stresses in the dam body under normal operating conditions. Improving the designs of massive dams is aimed at improving their stress-strain state (SSS) and, above all, the upstream face and the contact zone of the foundation, to ensure the durability of concrete in the outer zones especially in harsh climates, and to increase seismic resistance and technology improvement. The realization of the potential advantages of rolled concrete (RCC) dams depends to a large extent on the harmonious combination of dam design and construction technology.
