| 摘 要： | 利用GPS-RTK技术，结合上海和苏北潮滩高程观测实践。提出利用现场实测潮位，结合岸上水准点建立RTK水准控制网，对潮滩的高程进行有效观测的新方法，并对观测结果进行验证与分析。结果表明，1）流动站与基准站距离在8km范围内，其测量结果的相对误差小于5％；2）该方法简便、易行，特别适合缺少水准点的潮滩地区；3）RTK技术与传统滩面高程观测方法有机结合，取长补短，为潮滩冲淤变化研究和海岸工程监测提供了一个全新手段，具有较大的推广价值。

| Abstract: | By means of the GPS-RTK technology, a new method for effectively observing the tidal-flat elevation is proposed and practised in the surveys in Shanghai and North Jiangsu. In the method, the in-situ observed tidal level and the on shore bench marks are used to set up a RTK net for leveling control, the observational results from the method are analyzed and verified, h shows that the relative errors in the observations within 8 km between the base station and the mobil station is less than 5%. This method is simple and convenient in practice, and especially suitable to the tidal-flat area where there are less bench marks. The method combines the traditional method for tidal flat elevation observation and the RTK technology to have one＇s adventages to make up the another＇s shortages. It provieds a new means to study tidal flat deposits and erosions and to monitor the shore engineering. It might be worthy to be extensively used. |
