Method and Accuracy of Circular Construction Declivity Survey Based on Intelligent Total Station

The stability and reliability of tall buildings are one of the focuses of people’ concern and declivity is one of the most important indexes in engineering construction. Besides, the reliability of observed results is subject to the precision of observation. A new surveying method for circular construction’s inclination based on the function of cylinder exocentric measurement for intelligent total station is provided in this paper, and the operating process as well as the calculating method is introduced. The precision is analyzed, and the rationality of theoretical analysis and the reliability of the measuring methods are illustrated by examples.
