Determination of Mechanical Properties of Compressible Soil in Littoral's Region of Cameroon: Depths Study of Soils Bordering the Wouri River in Douala.

This work deals to the determination of the expansion ratio ( ) and compression index ( ) of soil samples taken at several points around the Wouri coast river of Cameroon. These parameters are the most important soil parameters, necessary to be known before each building project. The undisturbed soils samples are taken at nine different points labeled as P1, P2... P9 at the depths varying from 5m to 9.5 m and distanced around 10 to 15 meters. These studies are motivated by the fact that in this region, mechanical properties of soil have huge effects on buildings. By plotting the void ratio as a function of the logarithm of the pressure, these mechanical parameters are found and compared to that obtained from the inner land of Cameroon, Yaounde town chosen as an example. As a result, this comparison has allowed us to classify the soil and give some practical advantages when carrying out civil engineering works such as buildings, bridges in coastal area.
