The Seismic Coefficient in Earth Dam Design

The limitations of methods of earthquake-resistant design of embankments based on pseudo-static analysis and incorporating a static seismic force designated by a seismic coefficient are discussed. It is suggested that both from considerations of soil behavior under cyclic loading conditions, and for purposes of assessing embankment deformations due to earthquakes, the development of a method of predicting dynamic seismic forces and their variations with time would provide a more reasonable approach for design purposes. A method of accomplishing this objective is suggested, and representation of the results by an equivalent simplified seismic force series is proposed. For embankments that can be considered to have a uniform shear modulus, charts are presented for determination of the equivalent seismic force series. It is pointed out that limitations in available dynamic response analyses require that some judgment be exercised in selecting design parameters. However, the results presented in the paper provide a useful basis for guiding this judgment. Furthermore, the results show that in designating seismic coefficients for design purposes, it is important to distinguish between embankments of different heights and material characteristics as well as different positions of the potential slide mass within the embankment.

Mechanics of Inclined Filters in Earth Dams

The effect of filters in earth dams is examined. It is found that the critical slip circle is a function of the upstream slope only. It is shown that the validity of rapid drawdown in highly impervious material has no effect on the factor of safety. A chart is given that can be used for the design of earth dams.

Uncertainties in Earth Dam Design

Some of uncertainties that enter into embankment design due to unexpected granulation and permeability performance of soil and methods used in designs by Corps of Engineers, at Terminus and New Hogan Projects are presented; areas in design of high earth dams in which engineer should take conservative course are examined.

The Design of Earth Dams

The object of this paper is to aid in establishing more scientific methods of designing earth dams. Six criteria for the design of such dams are presented. These criteria are practically axiomatic, and most engineers will agree that an earth dam which satisfies each and all of them will be safe.
