ABSTRACT
The Great Man-made River Project, which includes reservoirs, regulating tanks, and over 2000 km of prestressed cylinder concrete and ductile iron pipes, is one of the largest civil engineering projects in the world. This paper discusses some geotechnical aspects of one of the reservoirs, the Sirt End Reservoir, on the first phase, and some results of the geotechnical investigations on the second phase of the project.
At the Sirt End Reservoir, some geotechnical tests, compaction of sea water moisture conditioned soils and the possible rising ground water due to irrigation are discussed. On Phase 2 of the project, special mention of the problems of expansive clays and the foundation solution adopted is made, together with a brief discussion on ground aggresivity along the pipeline.
