摘　　要：乡村公路是交通公路网络中的重要组成部分,主要是服务远距离低速的交通。而乡村公路小桥涵作为乡村公路的重要节点工程,是控制乡村公路质量,决定公路路线走向的决定性因素。基于施工过程中,施工队伍工程经验不足,建设经费较低等客观情况,如何经济有效提升乡村公路小桥涵的耐用性和实用性是设计工作的重点。论文以笔者参与设计的襄阳市乡镇路网改造项目为例,总结乡村公路小桥涵的设计原则,将乡村公路小桥涵的结构设计、荷载设计和排水设计作为设计要点进行了详细阐述。为日后的工程建设提供参考。Rural road is an important part of the traffic network,mainly serving long-distance and low-speed traffic.As an important node project of rural highway,small bridge and culvert is the decisive factor to control the quality of rural highway and determine the direction of highway route.Based on the objective situation that the construction team is lack of engineering experience and low construction cost in the construction process,how to improve the durability and practicability of small bridges and culverts of rural roads economically and effectively is the key point of the design work.Taking Xiangyang town road network reconstruction project that the author participated in the design as an example,the paper summarizes the design principles of small bridges and culverts of rural roads,and expounds the structural design,load design and drainage design of small bridges and culverts of rural roads as the design points in detail,which provides reference for future engineering construction.
