| Abstract: | The traditional geometrical leveling is inconvenient in fluctuating area .This article discussed the viability of monitoring the vertical displacement in small area, using the common Total Station instead of second-class leveling. Base on the formula of precise trigonometric leveling, it discussed the error resources and accuracy in Short-distance. Observed data were acquired by the common Total Station, and then verified the reliability of this method. At last it also gave out several precise measures, strengths and weaknesses. |
