由于地形、地势原因,福建省公路总里程中山岭公路占有相当大的比例,经常要跨越河、溪及沟壑等,公路桥梁众多。据统计,截止2002年底,福建省有公路桥梁10322座,占全国桥梁总数的3.4%。在这些公路桥梁中,拱桥所占比例较大,且建造技术也有较高的成就,因此建国以来相当长的一段时间内,石拱桥是福建省公路桥梁的主导桥型,尤其是在20世纪60、70年代,石拱桥建设达到鼎盛时期。以专养公路为例,截止2002年底,福建省3729座公路桥梁中石拱桥就有1936座,占桥梁总数的52%。本文对福建省专养公路石拱桥现状情况进行分析,在此基础上提出相应的养护对策。
Due to the topography and topography, the total mileage of the highway in the province of Fujian occupies a considerable proportion of the Zhongshan Ridge Highway, often crossing rivers, streams, gully and the like, and there are many highways and bridges. According to statistics, as of the end of 2002, there were 10,322 highways and bridges in Fujian Province, accounting for 3.4% of the total number of bridges in the country. Among these highways and bridges, the proportion of arch bridges is relatively large, and the construction technology also has high achievements. Therefore, for a long time since the founding of PRC, stone arch bridges have been the leading bridge type of highway bridges in Fujian Province, especially in the 20th century In the 1970s, stone arch construction reached its peak. Take the specialized highway as an example. By the end of 2002, there were 1,936 stone arch bridges in 3729 highway bridges in Fujian Province, accounting for 52% of the total number of bridges. This article analyzes the status quo of stone arch bridge in Fujian Province and proposes corresponding conservation measures.
