Comparison of Analytical and Structural Behavior Results for Flaming Gorge Dam. A Water Resources Technical Publication

摘要

This report presents comparisons of results from trial-load analyses and structural behavior measurements for two loading conditions on Flaming Gorge Dam. Stresses and deflections from the analytical studies are compared with the results of measured data for each loading condition. Flaming Gorge Dam is a concrete arch structure with an axis radius of 650 feet. The height of the dam above the lowest excavation for the foundation is 502 feet. The length of the crest is approximately 1,180 feet. A plan, elevation, and sections of Flaming Gorge Dam are shown on figure 1. The dam is on the Green River near Dutch John, Utah. During the year, the dam is subjected to both daily and seasonal temperature variations. The period from October 9, 1963, to March 26, 1964, was selected for the investigation of the effects of seasonal temperature change. The reservoir water surface and tailwater surface remained very nearly constant at elevations 5932 and 5600, respectively. This loading condition permits an investigation of temperature effects on the dam.
