In view of the sea damaged problem of slope revetment structure with the accropode during the typhoon,the comprehensive inspection and evaluation of the revetment in the sea damaged section are carried out.Combined with the situation and reasons of the sea damage of the test section,the plan of repairing and strengthening is designed by making full use of the terrain after the sea damage,and it is verified by the physical model test.The main conclusions are as follows:the mass of the cushion block stone of slope revetment is the key factor to maintain the stability of the revetment block,and the required mass of the cushion block stone in the 2018 version of the design code for breakwater and revetment are correspondingly improved;the stability and wave overtopping amount of the revetment block under the gentle slope condition meet the specification requirements,but the relevant technical requirements for the block installation under the gentle slope condition should be paid attention to.
