Maapatojen kunnon arviointi. (Condition monitoring of earth dams)
In the research work the ageing of earth dams was investigated concentrating mainly in the effect of frost. The results of measurements and georadar soundings carried out indicates that the effects and depth of seasonal frost can be evaluated by the existing empirical formulae. Georadar can be used not only for determining frost depth but also in most cases to determine the possible concentrations of seepage water in the dam or in dam foundation. It seems that georadar can be used when the alternation caused by aging are investigated. The basics for an index system to evaluate the operational condition and safety of old earth dams. The system is based mainly on the surveillance results obtained from the official dam safety control program. A short evaluation of dam failure costs compared to maintenance costs is given.
