摘要

摘要: 海面倾斜与高程基准密切相关,它已经受到大地测量学界和海洋学界的重视.进一步讨论了大地水准的测量精度,指出了大地(几何)水准与沿海验潮资料的不符是由于海面的倾斜;分析了海面倾斜的机理,其中包括海流、海水密度分布、气压、台风引起的破碎波等的作用;提出了用海水异常密度的三维分布计算大地水准面的扰动,实质上它反映了海面的倾斜,该量占大地水准测量结果的73%,这进一步说明密度的异常乃是我国沿海海面倾斜的主要原因.

Abstract: There is a close correlation between sea level slope and height datum, in which geodesylists and oceanographers are interested.The accuracy of geodetic leveling is discussed.The existent difference between geodetic leveling and tide station is investigated, and this difference comes from the sea level slope, and the sea level slope mechanism caused by ocean current, air pressure and breaking wave is analyzed, the geoid disturbance computed by three-dimensional distribution of sea water density is presented and this disturbance materially reflects the sea level slope.According to the computation the disturhance quantity possesses about 73% of the sea level slope, which indicates that the density anomaly of sea water is primary cause of the sea level slope.
