Authors develop the existing action stress technique of the PC bridge to improve accuracy compared with a past technique by the stress reliease technique that uses full-field optical measurement method, and have confirmed the measurement precision. In the thesis it introduces the technique. And, it explains application to Post-tension PC composite I girder bridge where alkali aggregate reaction(ASR) was caused., 第20回プレストレストコンクリートの発展に関するシンポジウム 平成23年10月13日(木)・14日(金) 於函館, 第20回シンポジウム論文集, pp.473-478; 2011}, pages = {473--478}, publisher = {プレストレストコンクリート工学会}, title = {光学的全視野ひずみ計測法を用いた応力解放法によるASRが生じたポストテンションPC合成I桁橋の現有作用応力測定}, year = {2011} }
