This operation requires the treatment of soil by lubricants to facilitate the procedure of excavation. A possible use of this soil is limited by the effect of treatment on the hydromechanical properties of the soil. This work aims to study the effect of a foaming agent on the hydromechanical properties of clay soil. The injection of the foam agent in the soil leads to create a soil matrix in which they are incorporated gas bubbles. The state of the foam in the soil is scalable thanks to the degradation of the gas bubbles in the soil.</abstract> <index>Open Science Index 115, 2016</index> </article>
