Based on the practice of using SET2110 total station to build connection traverse in extremely narrow section of Tuohe Line for plane-control survey, this paper explains that the survey precision is still believable when the topography is very complex, the survey situation is very hard and the map strength is adverse.
本文通过对托河线极狭窄路段利用SET2110全站仪建立附合导线进行平面控制测量的实践,说明在极其复杂的地形、极其困难的观测条件和图形强度极为不利的情况下,测量精度仍然是可信的;同时指出了在相对高差很大的山区进行导线测量时应注意的事项。
