Study of Key Techniques for High Earth-Rock Dam with Earth Impervious Element

In this paper the result of the research project:"Study of high earth-rock dam with earth impervious element"in National Key Technologics R & D Programme during the Seventh Five-Year Plan is introduced synthetically. This result mainly contains the new concepts, methods and equipment for revealling and measuring the engineering properties of dam materials and clay intercalation in foundation rock, two large-scale software systems including main contents of earth-rock dam design and the analytical methods related, some new reasonabletypes or design principles for dam body structure, and modern quality control and manage methods of dam construction, etc.This research result had won first-class Award of National Science and Technology Progress.
