Preface

With the continuous development of social economy, the requirements of urban road construction are also constantly improving, and the problem of road water accumulation has become a serious disaster in urban roads, which will not only affect the normal use of municipal roads, but also shorten their service life. Based on this, this book mainly analyzes the optimal design of municipal road water supply and drainage.
    With the development of national economy and the acceleration of urban construction, people have higher and higher requirements on the transportation system. In particular, the development of municipal roads has an important impact on people’s normal life and vehicle driving safety. Problems in water supply and drainage will affect the traffic capacity of road locomotives, and may even cause vehicle slippage and traffic safety. At the same time, the long-term water accumulation of the road surface will erode the subgrade, reduce the strength of subgrade soil, and even lead to the overall damage of the subgrade. The effect of municipal road water supply and drainage engineering not only directly affects the urban road, flood control, environmental protection, but also directly related to people’s work and daily life, so it has an important position that can not be ignored. Therefore, in order to ensure the normal use of municipal roads, the normal operation of the city and people’s normal life, it is necessary to design the drainage works of municipal roads scientifically and reasonably.
    All in all, the design of road water supply and drainage engineering is an important guarantee for the service life and performance of municipal roads. The scientific and reasonable design of municipal road drainage system has an important impact on the function and service life of municipal roads. Therefore, when we design the municipal road water supply and drainage system, we should combine the actual situation and lessons, optimize the design scheme of the municipal road water supply and drainage system on this basis, so as to promote it to play an important role in the process of urbanization in China.

前 言

随着社会经济的不断发展，城市道路建设的各项要求也在不断提高，而道路积水问题已经成为城市道路当中的一个严重灾害，它不仅会影响到市政道路的正常使用，还会缩短其使用寿命。基于此，本书主要对市政道路给排水的优化设计进行了分析。
       由于国民经济的发展以及城市建设步伐的加快，人们对交通系统的要求也越来越高。 尤其是市政道路的发展对人们的正常生活及车辆的行驶安全都有着重要影响，给排水出现问题会影响道路机车的通行能力， 甚至可能会造成车辆滑移， 影响交通安全，同时路面的长期积水会对路基产生侵蚀，降低路基土强度，严重时甚至会导致路基的整体破坏。市政道路给排水工程效果的高低 , 不仅直接影响着城市道路、防洪、 环保问题 , 也直接关系着人们的工作和日常生活 , 因此具有不容忽视的重要地位。所以为了保证市政道路的正常使用、城市的正常运转、人们的正常生活 , 必须对市政道路的排水工程进行科学合理的设计。
       总而言之，道路给排水工程设计是市政道路使用寿命、性能的重要保障，市政道路排水系统设计的科学性、 合理性， 对市政道路的功能及使用寿命有着重要影响，所以，我们在进行市政道路给排水设计时要结合实际情况和经验教训，在此基础上对市政道路给排水系统的设计方案进行优化，以促进其在我国城市化进程的道路上发挥重大的作用。
