dcterms.abstract | 根据海面地形与高程基准的定义 ,利用全球重力场模型EGM96及GPS水准数据计算了香港主要高程基准面与黄海 195 6高程基准面的重力位差 ,实现了两个高程基准的统一。计算结果表明两个基准面的重力位差为( 8.36 6± 0 .76 5 )ms-2 ,相当于香港主要高程基准面低于黄海 195 6高程基准面 ( 0 .85 5± 0 .0 78)m ,由此推算两个高程基准点 (验潮站 )处的海面倾斜为香港高于青岛 0 .4 4m (相对于历元 1994 .9) ,这些结果与水准联测及海面地形研究成果一致。 | - |
dcterms.abstract | In the terms of the definitions of sea surface topography and elevation datum,by use of the global gravity field model EGM\-\{96\} and the GPS leveling data the difference of gravity potential between the basic height datum of Hong Kong and Huanghai 1956 mean sea level has been calculated,hence the two height datums has been united.The result calculated shows that the difference of gravity potential between these two datums is \{(8.366\}±0.765)ms\+\{-2\}which means that the basic height datum of Hong Kong is(0.855±0.078)m lower than the Huanghai 1956 mean sea level and it is deduced that the sea surface tilt at Hong Kong height datum point(tidal station) is 0.44 m(relative to epoch 1994.9)higher than that at Qingdao station.These results are consistent with the results from connection leveling and research on sea surface topography. | - |
