GEOTECHNICAL SITE INVESTIGATION OF SIGIRI, LOWER NZOIA FLOODPLAIN, WESTERN KENYA

Geotechnical investigations were carried out to establish the bearing capacity of the geological materials that occur at the site. The investigations involved an analysis of the properties of the materials in the area using soil mass characterization, river depth analysis, geotechnical testing and slope stability analysis. The investigations identified several key stability issues such as the depth to the firm foundation, the bearing capacity of the foundation rock, liability to liquefaction and the stability of the slopes.
