The paer introduces second-class sea-crossing leveling put into practice in Xiamen Haicang bridge.

介绍了二等跨海水准测量厦门海沧大桥的实施情况.

With the data of over-sea leveling obtained from Naozhou island and Dahuang Jiang, calculation and analysis are carried out. The paper presents the method of confirming tidal datum for the tidal station in the island with leveling and GPS techniques , and finally comes to the conclusion that the method is of real value .

利用湛江市硇洲岛和大黄江跨海水准测量项目所采集的实测数据进行有效的计算和较深入的分析,研究了GPS及水准联测实施跨海水准测量确定海岛验潮站基准面的方法,得出了有推广应用价值的结论。

The key of GPS leveling across sea is that the height datum on each side of channel is not consistent,so the general geometrical fitting method can not be used directly.In this paper,a new method based on vertical deflection is used to solve the question,in which GPS leveling is used to determine surface deflections on each side of obstacle separately, afterwards surface deflections used to compute height anomaly difference between both sides of a river.The precision of a trial across an obstacle in width of...

The key of GPS leveling across sea is that the height datum on each side of channel is not consistent,so the general geometrical fitting method can not be used directly.In this paper,a new method based on vertical deflection is used to solve the question,in which GPS leveling is used to determine surface deflections on each side of obstacle separately, afterwards surface deflections used to compute height anomaly difference between both sides of a river.The precision of a trial across an obstacle in width of 10 km is close to Ⅱgrade leveling.

GPS跨海水准的关键问题是海峡两侧的高程基准不一致 ,因此无法采用常规的数值拟合方法。新方法从垂线偏差入手 ,首先采用 GPS水准分别测定海峡两侧的地面垂线偏差 ,再由所求垂线偏差计算跨海峡的高程异常差。 10 km宽度的跨障碍试验达到了接近二等几何水准的精度
