Instrumentation for Observations of Concrete and Soil Dams and Their Foundations (Apparatura dlia Nabliudenii za Betonn'mi i Gruntovmi Plotinami i ikh Osnovaniiami),
Abstract
Field observations of the condition of hydrotechnical structures play an important role in ensuring the safety and reliability of structures. Primary information about the condition of structures is obtained with the aid of measuring instruments installed in the structure. Such instruments have different purposes. Large modern structures contain up to 2 - 3 thousand units of instruments which measure physical values that characterize the stress-deformed state, linear and angular displacements, the temperature and filtration regimes of operation of the structure and of its foundation. Both optical-mechanical measuring instruments and measuring transducers with an electrical signal are employed. The fundamental developmental tendency of measuring instruments for hydrotechnical structures consists in the development of automated measuring devices and their gradual replacement of mechanical measuring instruments. Evidently, in the near future the role of the latter will be reduced chiefly to testing the automated measuring systems. (Author)
