  • Performance of shallow footing on geocell reinforced clay bed using experimental and numerical studies, Hegde and Sitharam (2012)

    Construction in soft, weak ground requires treating large areas to a greater depth to ensure the safety of the superstructure. Usually, deep foundation techniques or ground improvement techniques are applied. However, this usually proves to be very costly. Past research has demonstrated that geocell reinforcement increases the load carrying capacity of the foundation bed. It is also a ...
