摘要
针对目前海岸线确定技术多样的现状进行了基于粉沙淤泥质海岸潮滩海岸线实地测量的研究。应用CORS联合全站仪作业的测量模式获取潮滩海岸线上特征点的大地高,讨论了该测量模式的最佳测量场景。最后将选取的2013—2015年间潍坊港验潮站部分验潮数据与实测数据统一归算到1985国家高程基准。验证结果表明:实测潍坊地区潮滩海岸线正常高2.77 m,与验潮数据互差不超过3%。
Aiming at the current situation of the different technologies of coastline determination,this paper studies the tidal flat coastline field measurement based on silty sand coast. In this paper,the geodetic height of the characteristic points on tidal shoreline is measured by CORS combined with Electronic Total Station and have made a discussion about the best measurement scenario of the measurement mode. Finally,take the partial tidal data selected from Weifang port tide gauge station during 2013 ~ 2015 and the measured data together calculated to 1985 National height datum,the verification results show that the normal height of tidal flat coastline in Weifang area is 2.77 m which have a difference no more than 3% compared with tide data.
