Arch Dams: Design and Observation of Arch Dams in Portugal

Journal of the Power Division, 1956
Design, model testing, and field observation of six arch dams ranging in height from 60 to 135 m, enabled later designs to be modified to gain increased economy with safety; model studies determined stress conditions at irregularities in foundation and around special structures in arch.

Development of Arch Action in Arch Dams

Journal of the Power Division, 1965
Considering hydrostatic pressure as the only external load on an arch dam, the influence of the reservoir elevation and the elastic deformability of the foundations is investigated using the crown cantilever method. The arch and cantilever action are evaluated on the basis of a shear and moment criterion, representing the relative magnitude of the ...

Arch Dams: Economy of Concrete Dams

Journal of the Power Division, 1957
Safety and economy are considered in studies associated in final selection of type for large concrete dams; selection is further influenced by arrangement of dam and appurtenant works; pertinent unit cost data obtained from sources in various countries.

Arch Dams: Design and Construction of Ross Dam

Journal of the Power Division, 1956
Ross Dam is most important unit in hydroelectric development of Skagit River; entire system includes Ross, Diablo, and Gorge powerplants; generating capacity of 580,000 kw, Diablo Lake, having storage capacity of 90,000 acre-ft, and Gorge High Dam Reservoir, which has storage of 6000 acre-ft, serve to supply hydrostatic head for their respective plants.

Analysis of Arch Dams

Journal of Structural Engineering, 1993
A theory for arch dams based on extended shell theory is given and compared with finite-element-shell and three-dimensional (3D) analyses. The dam equations given are solved by successive overrelaxation. In a flexible valley, stress boundary conditions are used. Various loading cases and the pore-water-pressure effect are discussed.
