Study of elevation benchmark transfer technology based on dynamic level method

介绍了海岛高程的基准传递方法,论述了基于动力水准法的高程基准传递技术和原理,利用实测数据与三角高程法测量结果进行比较,得出了一些有益结论。并据此解决同步验潮场地勘选、验潮时机和时长等关键技术问题,构建理想的同步观测环境,缩短野外测量时间,提高基准传递精度。

The author made an introduction on the island elevation benchmark transfer method, and discussed the elevation benchmark transfer technology based on dynamic level method. The data measured with this technology was compared with that made by triangular elevation method, and some useful conclusions were drawn. The key technical issues such as site survey, measurement timing and measuring duration were resolved. An ideal synchronous observation environment can be constructed, the field measurement duration shortened, and the accuracy of benchmark transfer improved.
