Professor Sangseom Jeong's research lab specializes in geotechnical and pavement engineering, focusing on the behavior of soils and infrastructure under dynamic and environmental loads. Key research directions include landslide mechanisms in partially saturated soils, lateral load response of offshore piles, and the dynamic performance of asphalt pavements under varying traffic conditions. The lab integrates experimental testing, field monitoring, and advanced numerical modeling to develop practical design frameworks for geotechnical systems and flexible pavements.

This paper investigates rainfall-induced landslides on partially saturated soil slopes using the 2011 Umyeonsan landslides at the center of Seoul, Korea. An integrated analysis of rainfall-induced landslide was carried out through laboratory tests, field tests, and numerical analysis. The results of comprehensive investigations in the Umyeonsan region demonstrate that landslide activity is closely related primarily to rainfall and soil properties and slope geometry, and vegetation. Numerical ana
The load distribution and deformation of offshore piles are investigated using experimental tests and a numerical analysis. Special attention is given to the soil-pile rigidity of laterally loaded piles. Rigid-and flexible-pile analyses were conducted for comparison. A framework for determining the lateral load transfer curve (p-y curve) is proposed from field and laboratory model tests. A numerical analysis that takes into account the proposed p-y curves was performed for major parameters on pi
