The application the semi-vertical hydraulic revetment, a new port engineering structure, is still in the stage of exploration. This type of revetment structure is built on soft foundation, its foundation deformation characteristics has a great difference with that of the vertical type. In addition, the loading method and size is controlled strictly in soft foundation. Based on field loading test and on-site monitoring of foundation deformation of the semi-vertical hydraulic revetment, we compare and analyze the foundation settlement in different field test conditions and discuss the settlement and failure mode of the foundation.
