【摘要】：农村公路桥梁对于保障农村公路交通的贯通和经济的发展具有重要意义。为了了解我国农村公路桥梁的安全可靠性现状,以江苏省徐州市的县、乡道农村公路桥梁为例进行了较为全面的调查和统计。调查表明,尽管多数桥梁能够满足正常使用,但是已经存在明显安全隐患或者需要立即采取安全防护措施的四类桥和五类桥已占到桥梁总数的近40%,已经严重危及了桥梁的正常使用和行车安全,应给予高度重视。分析认为,设计标准偏低和超负荷使用是造成当前农村公路桥梁毁损的主要原因,而桥梁自身的质量、老化和日常维护管理的缺乏也是造成农村公路桥梁毁损进一步加剧的重要原因。最后对如何保障农村公路桥梁的安全使用提出了一些建议。
[Abstract]:Rural highway bridge is of great significance to ensure the rural highway traffic and economic development. In order to understand the present situation of safety and reliability of rural highway bridges in our country, a comprehensive investigation and statistics on rural highway bridges in Xuzhou City, Jiangsu Province was carried out with the example of rural highway bridges in Xuzhou City, Jiangsu Province.

The analysis shows that the low design standard and overload are the main causes of the damage of the rural highway bridges, and the quality of the bridges themselves. Aging and the lack of daily maintenance and management are also the important reasons for the further deterioration of rural highway and bridge damage. Finally, some suggestions on how to ensure the safe use of rural highway bridges are put forward.
