摘要
针对采用扭王字块护面的斜坡式护岸结构在台风期间发生海损问题,对海损段护岸进行了全面检测评估。结合检测断面海损情况及原因,充分利用海损后地形进行了修复加固方案设计,并通过物理模型试验进行验证。主要结论为:斜坡式护岸垫层块石质量是维持护面块体稳定的关键因素,2018版防波堤与护岸设计规范对垫层块石质量要求也相应提高;缓坡条件下护面块体的稳定性和越浪量均满足规范要求,但应注意缓坡条件下块体安装的相关技术要求。
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.
