In geotechnical engineering, it is crucial to evaluate the interaction between structural loads and soil properties to ensure the stability and safety of foundations. In this scenario, the column is subjected to a load of 120 tons, with an additional 10% safety factor added, resulting in a total load of 132 tons at the foundation base. The foundation base is designed with dimensions of 2.5 meters by 2.5 meters, and the load intensity applied to the soil must be carefully assessed to avoid excessive settlement or failure. The required bearing capacity of the soil is calculated to be at least 25 t/m², which must exceed the applied load intensity to maintain foundation stability. When dealing with weak soils, where the bearing capacity is as low as 10 t/m², the risk of foundation settlement increases significantly. In such cases, the reduced bearing capacity can cause differential settlement, affecting the structure’s performance. The amount of settlement is influenced by the bearing capacity of the soil, the depth of the foundation, and the total applied load. In this case, the soil has a unit weight of 1.85 t/m³, and the foundation is placed at a depth of 1.3 meters. Geotechnical engineers must ensure that the settlement remains within the permissible limits, which are 40 mm for sandy soils and 65 mm for clayey soils. Failure to control settlement can lead to structural problems such as cracking or tilting. Therefore, proper analysis of soil properties, load distribution, and foundation design is essential in geotechnical engineering to ensure long-term stability and prevent settlement-related issues.
