APPL ICATION OF TRIGONOMETRIC LEVEL ING IN SEISMIC MICROZONATION

On basis of analysis on trigonometric leveling in seismic microzonation of Shouguang, this paper propose a method of replacing the 5 grade leveling by triangulated height surveying of 2"total station, the accuracy reaches the 5 grade leveling and can achieve the requirements.Using this method, designing different leveling according to different project requirements can improve work efficiency, speed up the work progress.
