| 摘 要： | 林区不同结构类型的桥梁,由于设计、施工、维修养护等诸原因,经过长期的车辆运行,存在着不同程度的破坏和损伤,承载能力及通过能力难以满足现行荷载和日益增长交通量的需要,迫切需要改建或加固补强。本文阐述了林区桥梁改建加固的实用价值和经济效果,并根据其特点介绍了几种可行方案。同时据丰林大桥静、动荷载试验及外观检查结果,提出了加固补强的具体方法。

| Abstract: | After a long period of use, the bridges of different structural types in forest areas are damaged or injured in different degree because of the problems of design, construction and maintenance of bridges. The bearing capacity and the traversing capacity are not enough to support the present loads and the increasing traffic discharge. Therefore the reconstruction and the reinforcement of bridges are needed. The practical value and the economical effect of reconstructing and reinforcing bridges are described in this paper, and some feasible plans are also given. Based on the results from the static and dynamic test, and the appearance check of Fenglin bridges, some concrete methods for reinforcing bridges are proposed, too. |
