| 摘 要： | 本文以我国1985年《公路桥涵设计规范》和2004年《公路钢筋混凝土及预应力混凝土桥涵设计规范》为设计依据,采用汽车-超20级、挂车-120和公路I级两组荷载进行设计,同时考虑混凝土碳化和钢筋锈蚀等因素,对比分析了旧有桥梁的承载能力,为旧桥加固提出了几点建议。

| Abstract: | The paper is based on China's 1985 Highway Bridge Design Code and 2004 Reinforced Concrete and Prestressed Concrete Highway Bridge Design Code,and adopting the automobile-super 20 and road trailer-120 and highway I two groups of loads to design and at the same time taking into account effects such as the concrete carbonation and steel corrosion,the paper comparatively analyzed the bearing capacity of the old bridge and proposed some suggestions for the strengthening of the old bridge. |
