The choice of the structure to construct according to the type of soil (lift) requires specific analyzes related to soil geotechnical behavior.
The study is carried out on the basis of tests carried out in situ by the geotechnical laboratory of the OFFICE DES ROUTES along the Lubumbashi River. This allowed us to classify the soil and to reveal the different layers that constitute it, to reveal certain physical parameters on the one hand, and to know the permissible constraint on the other hand in order to size our structures.
At the end of these studies it was retained that the soil surrounding the sheet pile curtain includes three layers at different depths, namely the laterite (a filler material), silt and dense sand.
Our study is carried out in two phases, the first phase concerns the study of the soil while the second and final is concerns the choice of the structure to construct according to the type of soil (lift), since the structure did not exist yet.
