The results show that the damages to the appearance of concrete structures exposed to atmosphere , including honeycombing , cracking along rebar , rebar corrosion , and concrete delamination , are quite serious , that the poor quality of concrete construction , the insufficient thickness of local concrete cover , and the rebar corrosion expansion and dilatancy induced by carbonization of concrete cover are the main causes , and that the main form of damages to the overflow structure is the abrasion resulted from water scouring
结果表明，水闸的水上（大气中）混凝土结构外观破损十分明显，露石露砂、顺筋裂缝、钢筋锈蚀、混凝土破损剥落等已十分严重；引起破坏的主要原因是混凝土施工质量较差，局部保护层厚度不足，混凝土保护层碳化引起钢筋锈蚀胀裂，而水流冲刷磨蚀是水闸过流结构破坏的主要形式。
