根据第一、三、四航务工程局和南京水利科学研究所历年来对沿海港口工程混凝土和钢筋混凝土建筑物破坏原因的调查、观测和试验结果证实,影响我国海港工程混凝土耐久性的主要因素,在北方是天然的冻融破坏,在南方是海水氯盐渗入混凝土内部所引起的钢筋锈蚀。本文根据天然条件下港工混凝土冻融破坏和钢筋锈蚀的研究,并结合暴 According to the investigation, observation and test results of the failure of concrete structures and reinforced concrete structures of coastal port projects over the years over the years by the Engineering Bureau of the First, Third and Fourth Navigational aids and the Nanjing Institute of Hydraulic Research, the main factors affecting the durability of concrete in the harbor engineering of our country are confirmed. In the north is a natural freeze-thaw damage, in the south is the corrosion of steel caused by the infiltration of seawater chloride into the concrete. Based on the natural conditions of Hong Kong workers freeze-thaw damage and corrosion of steel reinforcement, combined with violence
