摘　　要：随着城市交通量日益增长,人们越来越关注交通出行安全,余宽C值是道路工程建筑限界中的重要组成部分,直接影响驾驶感受及行车安全。在我国城市道路、公路规范体系中规范均有规定,但不同规范对于余宽C值却均有不同,而国内外对侧向余宽的研究相对较少,为进一步理清余宽C值在规范体系的要求、工程建设中应用情况及存在的问题,本文通过对公路、城市道路规范对侧向余宽的相关规定及设置要求,比较公路、城市道路规范的异同之处,并梳理在道路、桥梁、隧道等工程建设中存在的常见的余宽问题,提出余宽在设计、工程建设及管理中的建议与策略。With the increasing traffic volume in cities,people are paying more and more attention to traffic safety.The clearance C value is an important component of road engineering construction limits,which directly affects the driving experience and safety.In the normative system of urban roads and highways in China,there are regulations on the value of the clearance,which are different in different regulations.However,there is relatively little research on lateral clearance at home and abroad.In order to further clarify the requirements of the clearance C value in the normative system,as also the application and existing problems in engineering construction,this paper compares the similarities and differences between highway and urban road regulations on lateral clearance,and summarizes the common clearance problems in road,bridge,tunnel and other engineering construction.The paper proposes the suggestions and strategies for the design,engineering construction,and management of clearance.
