摘　　要：通过总结酸雨侵蚀混凝土材料的相关试验研究成果,考虑了混凝土损伤和钢筋的锈蚀,提出混凝土受弯构件在受酸雨侵蚀下的承载力的计算公式,并与试验对比。结果表明:提出受酸雨侵蚀的混凝土受弯构件计算公式与试验结果吻合性较好,可为西南酸雨地区腐蚀结构的防护提供指导。By summarizing up the relevant test results of concrete material corroded by acid rain,the bearing capacity calculation model of concrete flexural members under the acid rain erosion is derived,based on the concrete damage model and the reinforcement corrosion model.The calculated model value of bearing capacity is in good agreement with the test data.The results provide theoretical basis for the structural protection reliability by the acid rain in southwest.
