Engineering-geological properties relative to dam foundation water-holding in different geologic enviroments

Abstract

The engineering-geological properties and the general groutability of different rock masses for the water-holding purpose can be deduced from the numerosity of numerosity of analysed permeabilities, fissuring, experimental and completed grouting works for dams in different geologic environments. This experience is significant and useful extension of prospectings for specific structures and a good basis for monitoring and maintenance of completed works, particularly in view of the long and costly construction of grout curtain as important safety components any dam. This work considers several types of rock masses: limestones, flysch deposists, volcanic rocks, and low metamorphic rocks, and summarizes investigaton results arid grout curtain information for some case examples.
