Full-scale investigations of high concrete dams under rigorous climatic conditions
An evaluation of the operation and condition of large hydraulic structures under rigorous climatic conditions can be accomplished by means of full-scale investigations and observations. This includes investigations of the temperature regime, stresses, cracking, opening of joints, displacements, of the structure and rock foundation, and percolation and ice regimes.
Full-scale investigations and observations on the Mamakan, Bukhtarma, Ust'-Kamenogorsk, Bratsk, and Krasnoyarsk dams revealed a quite considerable role of thermal effects on the static operation of structures located in a rigorous climatic zone: on their stress state, displacements, and percolation. Simultaneously difficulties were revealed in the performance of full-scale investigations related with the specific operating conditions. The experience obtained showed that a number of problems of the method and equipment of full-scale investigations and observations under rigorous climatic conditions require further elaboration.
