Abstract
Skirt-suction foundation consists of the cylindrical thin walls, which are sunk into the seabed by applying suction inside the skirt compartment. In this paper, a new method of predicting penetration resistance of skirts under various ground conditions is proposed by taking account of effective stress change of the inside and outside of the foundation ground. Appropriateness of the method is verified by comparing the calculation with the field observation of an actual skirt-suction foundation. Consequently, it is clarified that the proposed method can be successfully applied to predict the penetration resistance of skirt-suction foundations.
