茂名港博贺新港区防波堤工程防台措施设计

摘要

The breakwater in Maoming harbor area of Bohe port is consisted of revetment and allowable wave overtopping breakwater. Because the construction sequence has been changed, backfill material behind the revetment can’t be constructed in time, so the inner slop of revetment will be exposed to the open sea. Since the design condition has been changed, the structure type of inner slop will be different from the conventional structure. The project has experienced three typhoon processes. The reasons are summarized as follow: because of huge waves and typhoon surge, the top of breakwater is damaged during construction time. According to the characteristic of typhoon, making measures about top protection and inner slop protection, which are certain references to similar project.%茂名港博贺新港防波堤由护岸段和越浪段防波堤组成，由于建设时序的变化，护岸段后方回填未能及时实施，内坡在施工期将暴露在外海，这种设计条件的变化，使得护岸段的内坡结构不同与常规结构。同时结合工程经历的三次强台风过程，分析了台风期由于增水和浪大造成施工期防波堤堤顶损坏的原因，针对台风特点，制定了相应的堤顶和内坡防护措施，为今后类似工程建设提供一定的参考价值。
