This work is a contribution to the knowledge of the geotechnical characteristics of soils of Baraka and especially at port Mushimbakye. We present the results of tests of permeability in situ, of compaction, of granulometric analysis, of Atterberg limits and of direct shear tests. All these have helped to classify the soil of Baraka silty loam, moderately plastic and hard, bad qualities but good for compaction and construction. These soils are stable and of high permeabilities. Here permeability In situ varies according to the texture and soil moisture. We also present the studies of foundation at the port of Mushimbakye and MWAMBANGU. To these sites, allowable stresses are large and the insoles squares are the only that can withstand large loads. A Mushimbakye and Mwambangu the allowable stresses are respectively for square footings 218.1KN / m
