Assessment and prediction for service life of water resources and hydropower engineering

Abstract

There are a large number of in-service water resources and hydropower engineering in the aging stage. It is an urgent problem how to assess and predict service life of water resources and hydropower engineering. The related theory and method need to be proposed to improve the safety management level and make the reinforcing, removing or downgrading decisions. The current achievements in the research are reviewed. The assessment criteria and system are analyzed. The methodological progress for assessment and prediction of service life is summarized. The future development direction is stated. The key problems and their approaches are related and analyzed. It is shown that the assessment and prediction for service life of water resources and hydropower engineering is a comprehensive research topic. To solve the problems in above field, it is necessary to integrate many theories, methods and techniques in other fields such as water resources and hydropower engineering, geotechnical engineering, construction materials, environmental engineering, cybernetics and computer engineering.
