Current state and problems of improving operational monitoring of the safety of hydraulic structures

  • Published:
Hydrotechnical Construction Aims and scope

Conclusions

The experience of on-site observations and investigations at large dams, particularly at the Krasnoyarsk and Sayano-Shushenskoe, shows that the main problems of improving the organization and conduction of such observations and investigations to increase their effectiveness are:

  1. 1.

    The development of an optimal (unified for construction and operational monitoring) layout of the telemetric MMA, which should lead to a reasonable reduction of the number of instruments.

  2. 2.

    Provision of high-quality installation of MMA and equipment of the control panels at all hydrostations under construction.

  3. 3.

    Improvement of the quality of sensors and frequency meters (periodometers) being manufactured.

  4. 4.

    Acceleration of the development of automated systems providing for both automation of measurements and processing and analysis of the data of on-site observations with delivery of signals about emergency and preemergency situations.

  5. 5.

    Provision of skilled inspection of the safety of hydraulic structures starting from the instant of the first filling of the reservoir.
