摘要
随着混凝土结构使用年限的增加,其耐久性问题日益严重,不仅给国家造成了巨大的经济损失,而且影响了人民的生命安全。因此,迫切需要对不同地方的混凝土结构耐久性进行评估。参照相关规范,并根据寒旱地区混凝土结构的特点,建立了寒旱地区混凝土结构耐久性评价指标体系。用层次分析法确定指标的权重,用灰色聚类法对混凝土结构耐久性进行评估。并通过实例说明了该方法的实用性和科学性。该评价模型将定量因素实测值应用到评估中,提高了评价结果的准确性,为制定合理的混凝土加固维修方案提供依据。
With the increase of service life of concrete structure, the durability problem is becoming more and more serious, and not only has caused the huge economic loss to our country but also has affected people＇s life and safety. Therefore, it is urgent to evaluate the durability of concrete structure in different parts. The paper establishes the evaluation index system of durability of concrete structure that is based on the related specifications and the characteristics of concrete structure in cold and drought area. The analytic hierarchy process is applied to obtain weights of indexes and the grey clustering method is used to evaluate the durability of concrete structure. At last, the example is adopted to verify the practicability and science of the method. The measured values of quantitative factors will be applied to the evaluation in the model, which improves the accuracy of the results of evaluation and provides the basis for making the reasonable maintenance programs of concrete reinforcement.
