武汉市二等水准复测的实施精度及其地学意义

The Precision of Wuhan Second-class Level Remeasurement Web and Its Significance in Geography

武汉市原二等水准网的基本状况和使用的矛盾、复测网的实施和精度、高程变化的地学意义等几个有关问题进行了分析,从而认为,进行周期复测和增设基岩水准点对提高水准网精度有着十分重要的作用。

This paper discusses and demonstrates these problems, such as the basic conditions and antinomy in using of the older second-class level web of Wuhan urban, the implement and its precision of remeasurement web, and the significance of elevation-transformation and etc. It concludes that it is very important to increase the precision of level web that remesuring periodicity and increasing level points on rock should be carry through.
