GEOTECHNICAL INVESTIGATION OF SOILS: A CASE STUDY OF GOMBE TOWN (SHEET 152NW), NORTH EASTERN NIGERIA (2012)
This work focuses mainly on the Geotechnical properties of mapped areas in Gombe town which forms part of the Upper Benue trough. Representative soil samples were collected from these areas and were investigated for their Geotechnical properties with a view to classifying for their suitability or otherwise for infrastructural development. Hitherto, this has not been done in the Gombe town area. The recent growth which is associated with urbanization in Gombe Township calls for appropriate geotechnical investigation of soils of the area. Twelve representative samples were collected from different locations of the mapped areas around Kanol, Hamatatu, Wurro Daji, Kalshing Forest, Titi Baba, Chongo, Danba, Wurro Ladde, Pantame, Tempure, Tonde, and Kulalum. Samples from each site were collected at 1m depth and analyzed using the following tests: Moisture content test, Particle size distribution test, Atterberg limit test, Specific gravity test, Compaction test. All these tests were carried out using the BS 1377, (1990) Parts 1 - 9 specification. Based on the test results obtained from the study areas, comparison were made with some standard specifications and it was revealed that samples from Pantame, Hamatatu, Tonde, Chongo and Kulalum areas are clayey soils which are unsuitable for most engineering construction because they have poor bearing capacities. While soils from Kalshingi forest, Titi baba, Wuro ladde, Danba, Tempure, Kanol and Wuro Daji are clayey sands. This group would make better sub-grade materials for civil engineering construction.
