在设定的人工气候氯盐腐蚀的环境下,对同一水灰比的钢筋混凝土梁进行了腐蚀时间不同的试验研究,分析了氯盐腐蚀后的钢筋混凝土梁的承载能力及钢筋锈蚀率。结论表明,同一水灰比的混凝土梁在不同腐蚀时间下的承载力与氯离子在混凝土中的侵蚀深度及其对钢筋腐蚀的程度密切相关:氯离子侵蚀越深,导致钢筋锈蚀越严重,承载力下降越明显。 Under the setting of artificial salt and chloride corrosion environment, different corrosion time of reinforced concrete beams with the same water-cement ratio was studied. The bearing capacity of steel reinforced concrete beams with chloride salt corrosion and the corrosion rate of steel bars were analyzed. The results show that the bearing capacity of concrete beams with the same water-cement ratio at different corrosion times is closely related to the chloride ion corrosion depth in concrete and its effect on corrosion of steel bars. The deeper the chloride ion erosion, The more obvious the decline in force.
