碩士 === 明新科技大學 === 土木工程與環境資源管理系碩士班 === 102 === This Study is to analyze pier structural safety of the Taiwan High Speed Rail (THSR) structure through the inclined displacement measurements. These displacements are induced from construction vibration nearby the Chu-Tung water channel project. The Tiltmeter was used to monitor the displacement of the pier and record the readings of it. By using the measured data and statistical analysis results, it is intended to discover any deterioration occurred in the pier structure due to the nearby construction. In this investigation, inclined displacements of THSR piers were statistically analyzed during the construction as compared with those of non-construction stage. It is shown that very small variation was observed on the measured data and the inclined displacements are quite smaller than the regulated limits. This findings can be used as related reference for the THSR project. Keywords： Tilt, THSR, initial value, observed value, pier, inclination
