Abstract
The development of continuous and automatic quantitative monitoring methods will improve bridge construction. This paper proposes a method for estimating vertical bridge displacement during construction based on the Bayesian inverse problem. The proposed method is applied to a bridge under construction in Japan. Case studies suggest that the observed rotation angle is more important than the observed strain for the estimation of vertical displacement. Based on strain and rotation angle measurements, vertical bridge displacement was estimated with an accuracy of less than 2 mm, as determined from a comparison with displacements obtained in a leveling survey. The 95 % confidence interval of the estimation error is consistent with the scatter of measured data of displacement, rotation angle, and strain.
