摘要
随着现代交通的发展,高速公路部分桥梁无法满足日益增加的使用要求,出现了不同程度的病害。文章以云南楚大高速为例,对高速公路空心板桥病害特点进行分析,并从技术、经济和施工方面对整体换梁和梁端加固两种方案进行比选,推荐选用梁端加固方案。
With the development of modern traffic, the highway bridges can not meet the increasing demand for the use and appears different degrees of disease. In this paper, taking Yunnan Chuda expressway as an example, diseases characteristics in hollow slab beam bridge are discussed, treatment schemes of girder replacement intergrally and beam-end reinforcement are compared and selected from aspects of technology, economy and construction, and beam-end reinforcement is proposed.
