| 摘 要： | 在三峡工程明渠截流进程中,截流戗堤左右头平面位置是一个动态轨迹。采用Trimble激光全站仪配合清华山维EPSW98电子测绘系统实时监测戗堤口门水面宽,方便、快捷、可靠且测量精度高,并解决了采用人工施测可能造成的安全问题。还介绍了采用EPSW电子测绘系统在水下地形测量数据自动成图中的应用,大大提高了出图效率,减少了出错环节。

| Abstract: | The planar position of both sides of the dam front edges are always looked as a dynamic track during the course of opening diversion channel closure. It is convenient, speedy and credible for us to take advantage of Trimble laser top station, equipped with EPSW98 made in Qinghua Shanwei to monitor the water surface width between both edges of the dam at real time, at the same time, it also can present us the high precision survey products and safeguard in stead of manual operation. Moreover, in this paper, a kind of new brainpower cartography on making use of EPSW98 to process the under water terrain survey data is introduced, this method can not only enhance the plotting efficiency greatly, and can also reduce the probability of making mistakes. |
