 note = {本研究では，ASRによる劣化が確認された鋼橋のRC床版を対象として，試験車走行試験を行うとともに，一般車を対象とした走行荷重，床版変位などを長期モニタリングした．その結果，劣化橋梁上を走行する大型車の軸重変動が劣化を助長していることを明らかにした．また，一般車の走行荷重実態と解析結果を比較することにより，現状のRC床版が健全時と比較して著しく剛性が低下していことを明らかにした．, In the mountainous area of the Hokuriku region, bridges are experiencing early deterioration caused by salt damage, alkali-silica reactions (ASR), and frost damage. The reinforced concrete (RC) slab of a road bridge, which has deterioration caused by ASR, was investigated in this study. The vehicle running tests using a heavy test truck were also performed, and the displacements of the RC slab were measured. Long-term monitoring of the responses of the test bridge due to live load based on the bridge weigh-in-motion method was also performed for ordinary vehicles. Then, the stiffness of the RC slab was evaluated by comparing the results obtained from the tests and the numerical analyses. It was found that the stiffness of the slab remarkably decreased as compared with the results when the slab was sound., 研究課題/領域番号:16K06463, 研究期間(年度):2016-04-01 - 2019-03-31, 出典：研究課題「既設劣化橋梁の耐荷力性能に及ぼす軸重変動の影響評価と走行荷重特性の解明」課題番号16K06463
