rustiness

Based on large numbers of existing bridges, this paper analyzes and studies the dominant factors which affect the durability of the reinforced concrete bridges, such as the rustiness of reinforcing steel bar, the freeze-thaw cycle of concrete, the alkaline-aggregate reaction of concrete.

本文根据大量的已建钢筋混凝土桥梁的运营状况，分析研究了影响钢筋混凝土桥梁结构耐久性的主要因素，如钢筋的锈蚀、混凝土的冻融循环、混凝土的碱集料反应等；

Combining research findings on rebar rustiness and based on the above harvests, the discourse distribute weighings to subfield aggregate of sections concrete structural system and evaluate corrosion damage by the method of multilevel fuzzy synthesized estimation.

在上面研究成果的基础上，结合钢筋锈蚀的研究成果，对型钢混凝土结构体系的子域集进行了权重分配，然后采用了多级模糊综合评判的方法对结构体系的腐蚀损伤进行了评估。

This paper also brings forward the method to check and measure the disease of the reinforced concrete bridges, such as checking and measuring of crack, rustiness of reinforcing steel bar, deck pavement, carburized depth of concrete.

提出了钢筋混凝土结构病害的检测方法，如，裂缝的检测、钢筋锈蚀的检测、桥面铺装病害的检测、混凝土碳化深度的检测等；
