| Abstract: | This paper introduces a method of the optical micrometry in the measuring ofvertical control network for Humen Bridge. The four perts of the broad estuary rivercrossing leveling is completed in the slope from 1. 1km to 1. 4km in the estuary of Zhujiang River, with the extraordinary signal was made by themselves. The accuracy iswithin reach 2nd-order leveling of engineering survey. This is a simple and practicalmethod. |
