In the field of construction, performing laboratory tests of soil mechanics and geotechnics is a key step. Tests performed on undisturbed soil samples are sometimes required. The major difficulty in the success of these tests is in the prevention of any change in the state of these materials which may be due to coring, transport and sampling in the laboratory conditions. Physical factors, such as rainfall, temperature, are ones of the most which can change samples natural state. To facilitate obtaining the parameters of the mechanical behavior of undisturbed samples, this paper proposes to establish correlations between shear strengths of disturbed samples and those of undisturbed samples of tropical soils of Burkina Faso. Shear tests were performed using the Casagrande cell on disturbed and undisturbed samples from Kamboinsé; Loumbila and Saba sites. The tests carried out were Unconsolidated-Undrained; Consolidated-Undrained and Consolidated-Drained. For each test, linear correlation between shear strengths of disturbed and undisturbed samples was etablished under similar moisture content conditions. Results displayed a good correlation between shear strengths of undisturbed samples and those of disturbed samples. All correlation coefficients are greater than 0.9. Samples particles sizes distributions and their clay content did not have significant impacts on shear strengths.
