| 摘 要： | 从理论上讲，边角网同测边网相比能提高点位精度。如用ME5000测距仪测边，则测边精度很高，而方向观测精度一般只能达到0．5″左右，致使边、角精度匹配不合理，此时边角网与测边网比，提高精度很有限。对于东风水电站监测网来说，测边网的精度已能满足要求，不必采用边角网形式，这样既能缩短观测时间，又能节约经费。 |

| Abstract: | Usually. the range and angle control network is more accurate than the range control network. However. in a certain sense. the precision of the range and angle control network. compared with that of the network of trilateration. is not evidently raised. but the work load is largely increased. This article proves that the use of EDM equipment ME-5000 to trilateration will result in this situation. Therefore. for ME-5000. net of trilateration can be used as dam monitoring net. In order to increase the precision of graph. the article puts forward a way. |
