摘　　要：从江苏省沿海警戒潮位核定工作出发,对《警戒潮位核定规范》中核定岸段等级划分、波浪爬高复合坡度计算、数值模拟选取年极值高潮位过程三方面内容进行了探讨。指出各自存在的问题,分别为岸段划分等级结果偏高、复合坡度计算公式不满足适用条件、年极值高潮位选取有偏差。文章同时给出相应的解决方案或思路,供规范修订或警戒潮位核定时参考使用。Three aspects of the“specification for warning water level determination”for Jiangsu coastal warning water level are discussed, such as grade division of warning water level determination coast, composite slope calculation method for wave run-up, selection of numerical simulation for annual extreme high tide level. It is pointed that the grading results of warning water level determination coast is slightly higher, the composite slope calculation formula does not satisfy the applicable conditions, and the selection of numerical simulation for annual extreme high tide level has deviation. The corresponding solutions are proposed to those problems, and the conclusions can be used for specification revision or warning water level determination for reference.
