지반의 상호작용을 고려한 전면기초의 해석기법 개발 = Development of Analysis Method for Mat Foundations Considering Coupled Soil Springs

다국어 초록 (Multilingual Abstract)

The 3D numerical analysis is carried out to investigate the settlement behavior of flexible mat foundations subjectedto vertical loads. Special attention is given to the improved analytical method (YS-MAT) that reflects the mat flexibilityand soil spring coupling effect. The soil model captures the stiffness of the soil springs as well as the shear interactionbetween the soil springs. The proposed method has been validated by comparing the results with other numerical methodsand a field measurement on mat foundation. Through comparative studies, the settlement of the proposed method wasin relatively good agreement with those of a field measurement and other numerical methods. The results permit usto estimate the response of the mat foundation subjected to vertical loads that should be taken into account in thecombination of mat flexibility and soil continuity characteristics.
