ABSTRACT
The research object was high 120 m concrete gravity dam of the Angara Bratsk hydroelectric power plant. The state of the
concrete dam is estimated based on the results of continuous supervision
performed by site personnel as well as periodic monitoring. According to the
classification of the interrelations in the system “concrete-environment”, there were selected
some important parts of dams and a comprehensive analysis of concrete was executed on these
parts. Concerning the complex research of concrete, a combination of full-scale tests with core-sampling has been proposed.
Core samples tests had an object to study the deep concrete layers and to
determine the specific indicators such as strength, density, porosity,
comparative diameter of capillary pores, CaO content in cement stone and others. Obtained findings and
recommended criteria can be applied when selecting technologies for
constructing dams that guarantee their durability in the north.
