Abstract

 Monitoring deformations is a key technology for assessing the stability, predicting the risk, managing the safe operation, and reducing the project cost. Although various types of instruments and systems have been developed to achieve successful monitoring, those can be applied to measure one or two dimensional displacements only in local area during short term.<br> In order to overcome such limitations, a new type of GPS displacement monitoring system has been developed by the authors. It can continuously monitor the three-dimensional displacements of the ground surface automatically with high accuracy for long term. Besides it provides monitoring results through the internet in real time, and users can see them at anytime and anywhere.<br> In this paper, the system is outlined and the practical application results are described.
