Investigation of uplift pressures and shear and tensile strengths for concrete gravity dams
- Stone and Webster Engineering Corp., Denver, CO (USA)
This report presents a discussion of concrete gravity dam stability parameters such as uplift pressure and strength test results of lift joints and concrete-to-rock contact areas from several older dams. The purpose of the report is to present the importance of site foundation investigations in the interpretation of uplift pressure readings and to discuss the application of site test results to get the maximum benefit of actual conditions when submitting dam stability calculations for the consideration of regulatory agencies. Uplift pressure behavior and its response to reservoir level fluctuations are discussed with case study examples. The feasibility of using actual strength data from existing dams as a benchmark database to give credibility to site-specific values is demonstrated. 69 refs., 47 figs., 6 tabs.
