3.5 橋梁下部結構的加固
橋梁的下部結構是承受橋梁上部荷載、維護橋梁使用安全關鍵結構，在對橋梁下部結構進行加固的過程中，應當利用環氧樹脂、NSF改性砂漿等材料對結構表麵的裂縫進行灌注處理，並采用外加護套、粘貼鋼板或包裹碳纖維布等方法進一步提高橋梁下部結構的剛度與強度，增加結構的承重能力，確保公路橋梁的使用安全。
4 總結：
選用恰當的加固技術對公路橋梁進行維修與改造，能夠起到減輕橋梁病害、提高橋梁整體性能、延長橋梁使用壽命的作用，對我國交通運輸行業的發展起到了積極的推動作用。

3.5 橋梁下部結構的加固
橋梁的下部結構是承受橋梁上部荷載、維護橋梁使用安全關鍵結構，在對橋梁下部結構進行加固的過程中，應當利用環氧樹脂、NSF改性砂漿等材料對結構表麵的裂縫進行灌注處理，並采用外加護套、粘貼鋼板或包裹碳纖維布等方法進一步提高橋梁下部結構的剛度與強度，增加結構的承重能力，確保公路橋梁的使用安全。
4 總結：
選用恰當的加固技術對公路橋梁進行維修與改造，能夠起到減輕橋梁病害、提高橋梁整體性能、延長橋梁使用壽命的作用，對我國交通運輸行業的發展起到了積極的推動作用。
