漳州地区花岗石丰富,在上世纪60～80年代设计的桥梁中以石拱桥居多,且平坦拱所占比例较大,如今随着交通量的猛增和超限运输车辆的重荷,多数石拱桥所显现的病害基本相似,如主拱圈变形、开裂,扩大基础淘空,桥台位移、下沉等。文章通过长泰油车溪桥的加固实践过程,阐述在石拱桥类似通病的设计与施工技术,并提供可借鉴的建议。 Zhangzhou area is rich in granite. In the bridges designed in the 1960s and 1980s, most of the bridges were stone arch bridges, and the flat arch accounted for a large proportion. Nowadays, with the rapid increase in traffic and the heavy load of overloaded transport vehicles, most stone Arch bridge disease is similar to the show, such as the main arch deformation, cracking, expansion of the basic Amoy, abutment displacement, sinking and so on. Through the process of reinforcement of Changtai Youchexi Bridge, the article expounds the similar design and construction techniques of stone bridge and provides suggestions for reference.
