Abstract

Theoretical profile stress and displacement of a certain non-overflow gravity dam in a key water-control project was studied in this paper. Plane finite element method and dam-rock coupling effect were both considered. It is concluded that the tensile stress concentration was appeared at the heel and toe of dam, especially the dam heel with significant compression. Therefore, the former position is of great importance in the design. However, the stress is still less than the strength of dam concrete and foundation rock, which is means the seismic design of the non-overflow gravity is reasonable. Moreover, it is indicated that the dam-rock coupling effect will significantly affect the simulation results.
