Abstract
The foundation of any structure plays a pivotal role in ensuring its stability and durability. The soil beneath the foundation must possess sufficient bearing capacity to support the structure’s load, while also resisting the uplift pressure exerted by groundwater, especially in saturated conditions. Inadequate bearing capacity can lead to settlement or even structural failure. Additionally, the surrounding soil must be stabilized to prevent lateral movement and ensure the foundation’s long-term performance. By enhancing the strength of the soil around the foundation, it becomes more capable of withstanding lateral forces, including those transferred from columns. These columns, connected to the foundation slab, can generate overturning moments due to lateral loads. These moments must be balanced by the restoring forces provided by the stabilized soil. Thus, an effective foundation design must account for both vertical loads and lateral forces, ensuring equilibrium. The use of appropriate soil stabilization techniques is essential for ensuring the foundation’s ability to withstand these forces and maintain the structural integrity of the building.
Keywords: Lateral load on column, lateral thrust at foundation base, overturning moment, restoring
