Semi-vertical cylindrical revetment is a new port engineering structure. Field load tests on a semi-vertical cylindrical revetment is carried out based on its application of a hydraulic revetment in Dalian. The earth pressure, foundation settlement, horizontal movement and pore water pressure of the semi-vertical cylindrical revetment are monitored. The settlement and horizontal movement of foundation of the semi-vertical cylindrical revetment are analyzed, and its non-uniform settlement is further studied. The monitoring results indicate that the sensitive factors affecting the settlement of the semi-vertical cylindrical revetment are loading stage, loading intensity, loading duration and loading intervals. The final unsymmetrical loading behind the revetment has the greatest impact on the non-uniform settlement of cylindrical structure. The variation of pore water pressure is mainly affected by each loading, loading duration and tidal action. When the cylindrical structure is installed and the first level of loading is applied, there is a remarkable fluctuation of pore water pressure.
