In view of deep water and soft soil foundation, a new type of breakwater with cylindrical jacket and pile foundations is proposed. According to the hydrological and geological conditions of Tianjin Port, the stability and bearing capacity of breakwater are numerically simulated by ABAQUS software. The results show that when the pile is an elastic model, the failure of soil is the main cause of structural instability. In the limit state, the structure is unstable in rotation in addition to arc sliding, and its turning point is below the bottom of the cylindrical jacket and deviates from the structural axis near the front-pile side. When the pile is a damage plastic model, the loss of bearing capacity is the cause of structural instability. The safety coefficient is greater than 1, but it is obviously smaller than the one of elastic model. The research results provide a reference for structural design and stability study of the breakwater with cylindrical jacket and pile foundations.
