Welcome to Soil-Substructure Interaction Lab(SSIL) of Yonsei University. Yonsei SSIL has educated and accomplished countless achievements in the field of foundation of high-rise building, ling-span bridges, NATM tunnels and other infrastructures. Our lab educated and trained students to be the leaders in the field of foundation designing, and produced 9doctors, 41 masters doing their part in the society. And now, we are training 7 doctors, 6 masters-doctoral joint scholars and 4 masters. Current members of our lab are also doing their part, studying and researching, day and night. This website provides wide range of information

on curriculum of foundation engineering education, activities of graduate students, and programs related to the foundation research. We are always gratful for all the interests and love sent towards our Sol-Substructure Interaction Lab.
