摘　　要：粤东某抛石结构斜坡堤自建成后频繁遭受强台风袭击,护面结构多次受损,为确保防波堤主体结构的稳定性,需对防波堤薄弱位置进行加固,以提高其整体防护能力。在分析防波堤受损原因的基础上,根据新的规范要求及新的设计波浪要素,加强堤身结构断面设计,并通过物理模型试验进行优化比选验证,最终确定在既有定点随机安放的扭王字块护面结构上,增设1层大型扭王字块的加固方案。经工程实践验证,采用双层扭王字块进行护面加固后的防波堤结构整体稳定性好,抗风浪能力显著提升。该方案施工简便、可操作性强,适用于斜坡式结构防波堤的修复与加固,可供类似项目借鉴。A riprap structure slope breakwater in eastern Guangdong has been frequently attacked by strong typhoons since its completion,and the armour layer has been damaged many times.To ensure the stability of the main structure of the breakwater,it is necessary to strengthen the weak position of the breakwater to improve its overall protection ability.This paper expounds that the engineer has strengthened the section of the breakwater structure on the basis of analyzing the damage causes of the breakwater,according to the new specification requirements and new design wave elements,and has carried out optimization comparison and verification through physical model tests.Finally,the reinforcement scheme of adding one layer of larger Chinese accropode to the existing fixed-point random placement of the Chinese accropode is determined.The engineering practice has proved that after using double-layer Chinese accropode for reinforcement of the breakwater,the overall stability of the structure is good,its ability to resist wind and waves can be significantly improved.The scheme is simple and has strong operability.It is suitable for repair and reinforcement of mound-type breakwater and can be used as reference for similar projects.
