Promising Techniques in Geotechnical Engineering
Soil and its interaction with structural foundations is a cornerstone of geotechnical engineering, influencing the stability and safety of infrastructures. Whether dealing with seismic challenges, enhancing port capacities, or improving soil performance, modern engineering relies on innovative techniques and careful analysis to address these complex issues. The research of Dr. Selçuk Bildik (Department of Civil Engineering, Nisantasi University) explores two key areas—soil-structure interaction and soil reinforcement—highlighting advancements that blend experimental, numerical, and theoretical approaches to optimize foundation performance and ground stability.
Soil-Structure Interaction
The stability of geotechnical structures under seismic forces is critical, especially in earthquake-prone areas. Dynamic loads notably affect pile foundations, with factors like soil layers, groundwater, and pile material influencing stress and deformation. Earthquake magnitude is particularly impactful, as weaker soils amplify strain along the pile’s length [1]. Ports, essential for trade, benefit from hybrid pile designs that integrate reinforced and unreinforced elements. As seen in Guinea, these innovations supported crane loads without disrupting operations [2]. Vertical stress distribution beneath foundations also demands attention, with circular footings on sand showing stress variations based on size and depth. Experimental and computational methods refine design approaches, enhancing infrastructure safety and performance [3].
Soil Reinforcement and Ground Improvement
Soil reinforcement using geogrids enhances ground performance by improving bearing capacity, reducing settlement, and protecting buried structures like pipelines. Optimal geogrid configurations—such as specific depths and layer spacing—can significantly increase soil strength, cutting settlement nearly in half [4]. For structures exposed to uplift forces, like offshore platforms, geogrids nearly double the uplift capacity of anchors in sand [5].
Advances in soil-structure interaction and soil reinforcement enable the precise and efficient address of complex challenges. From seismic resilience to ground improvement, these methods combine traditional principles with advanced tools, ensuring safe and sustainable development. As global demands on infrastructure grow, such innovations will continue to improve geotechnical engineering.
