       道路的养护维修工作是维持道路正常运行的基本保证.我国的养护维修作业研究和实施还处于初级阶段，满足不了社会和经济发展的要求。

       本文通过对比国内外养护维修作业区构成、养护维修作业分类、养护维修

       作业安全研究和养护维修作业安全设施，介绍国外养护维修作业的先进经验，有助于我国发展养护维修作业研究和实施。

       本文通过对国内外养护维修作业警告区长度研究，利用标志设置的理论，提出一种养护维修作业警告区长度及其内标志间距离的计算方法。

       本文通过对夜间养护维修作业优缺点及决策因素的研究，提出一种利用“费 用-效用”模型理论分析夜间养护维修作业决策的方法。

    Road maintenance is the basic assurance of keeping normal operation of the road. The research and implementation of road maintenance work in our country which is still at initial stage can't meet the demand of social and economic development.

    The basis of comparing the composition of traffic control zone for maintenance work, maintenance work c1assification, maintenance work safety research and safety devices at home and abroad, this paper introduces the overseas advanced experience in maintenance work which will benefit our research and implementation in this filed.

    Secondly, through the length of warning area research for maintenance work at home and abroad, this paper puts forwards a way to calculate the length of warning are based on the theory of traffic signs setup.

    Thirdly, based on the research of advantage and disadvantage of nighttime maintenance as well as the decision factor, the paper brings forward a way of nighttime maintenance decision-making based on the theory model of "cost-efficiency".

Key Words: maintenance work, safety, comparison at home and abroad, warning area, nighttime maintenance work management
