Energy dissipation and erosion control of stepped overflow structure on key dam of gully correction 治溝骨干工程臺階式泄水建筑物的消能防沖研究
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 結(jié)果表明,水閘的水上(大氣中)混凝土結(jié)構(gòu)外觀破損十分明顯,露石露砂、順筋裂縫、鋼筋銹蝕、混凝土破損剝落等已十分嚴(yán)重;引起破壞的主要原因是混凝土施工質(zhì)量較差,局部保護層厚度不足,混凝土保護層碳化引起鋼筋銹蝕脹裂,而水流沖刷磨蝕是水閘過流結(jié)構(gòu)破壞的主要形式。
