The general objective of this research is to develop methods for analysis of stresses and movements in embankments. The analysis will provide an opportunity to evaluate the usefulness of the finite element method for conditions where 1 The calculations are performed before the dam is built 2 The dam rests on a considerable thickness of compressible clays and silts 3 There is considerable time delay in the movements due to consolidation of the foundation and 4 Because of the low strengths of the clays in the foundation of the dam, it will be necessary to build the dam in two stages, allowing time for consolidation of the foundation before the second stage is built. Settlements, horizontal movements, and the pore pressures will be measured in the foundation and the embankment of Birch Dam Osage County, Oklahoma during construction and after. When these measurements are available, an additional study will be conducted to compare the measurements with the predictions contained in this report. This follow-up study will provide a basis for evaluating the accuracy of the presently available finite element analysis procedures for a difficult set of conditions.
