English Abstract

There is a paucity of geotechnical information about the surfical soil of Sana'a region. Therefore, this study is aimed at filling this gap by studying in detail the engineering properties of Sana'a soil. The geotechnical properties of the surficial soils of an area of about 100 km in Sana'a region, the capital of Yemen Arab Republic were investigated. The study consisted of both field and laboratory investigation programs. In the field investigation program, 32 locations were selected for the classification and inspection tests. Based on the obtained results, ten additional stations were selected for carrying the standard penetrations test and for studying the geotechnical properties in more detail by carrying out specific tests. The laboratory testing program included classification tests, strength tests (consolidated undrained triaxial test), one dimensional consolidation test, X-Ray Diffraction analysis, X-Ray Fluoresence analysis, Energy Dispersive Spectrum, Scanning Electron Microscope analysis and chemical analysis. Based on these investigations seven different soil units, resulting mainly from both alluvial and wind depositional systems, were also identified. Depositional systems and soil distribution were identified. Soil profiles have been prepared. Soil composition, soil structure and engineering properties including index properties, strength properties and deformation characteristics were established. Preliminary analysis indicated the existence of both collapsing soil, loessial soil and expensive soil, top layer. Appropriate design considerations for the expected moisture conditions, suitable foundation implementation and finally potential improvement techniques of the soil in the region were drawn.
