Preface

With the rapid development of today’s society, the progress of urbanization is accelerating. There are more and more vehicles on the road, followed by the increasing number of roads and bridges, which makes people travel more convenient and greatly promotes the economic development and the progress of urbanization. However, the increase in the number of roads and bridges has also brought some problems. Most of the road and bridge projects are subject to strict engineering quality control in the early stage of construction, but to a certain extent, they despise the management and maintenance in the later stage, resulting in a large number of road and bridge projects not reaching the expected goal, and even seriously threatening people’s lives and property safety.
         Roads and bridges are closely related to people’s daily traffic. Only when the quality of roads and bridges is guaranteed can the city’s traffic run smoothly. With the continuous increase of traffic flow, it will not only cause the occurrence of highway bridge disease, but also make its continuous development and deterioration, reaching an uncontrollable level, seriously affecting the service life of the road and bridge, the safety of people’s life and property, the convenience of traffic and the image of the city. In the process of maintenance and management of road and bridge, there are many problems, such as unreasonable preliminary design of road and bridge project, lack of funds, backward technology and incomplete management, which will affect the service life of highway bridge and shorten its service life. Therefore, it is very necessary to take scientific and reasonable measures to improve the maintenance and management of highway bridges.
        The maintenance of roads and bridges plays an important role in promoting urban construction, providing convenience for people to travel and ensuring the safety of people’s lives and property. The road and bridge maintenance project needs to keep up with the development of the times, increase the attention of the masses to the road and bridge maintenance work, introduce new technology, increase supervision, increase capital investment, and ensure the healthy development of China’s road and bridge cause.

前 言

随着当今社会的快速发展，城市化进度不断加快，道路上行驶的车辆也越来越多，随之而来的就是路桥的数量在不断的增加，使人们的出行更加便利，也极大的促进了经济的发展和城市化的进度。但是路桥数量的增加也带来了一些问题，大多的路桥项目在建筑的前期受到严格的工程质量把关，却在一定程度上轻视了后期的管理和养护，导致大量的路桥工程达不到预期目标，甚至严重的威胁到了人们的生命以及财产安全。
       道路桥梁与人们日常的通行息息相关，道路桥梁的质量得到保障才能使城市的交通有不紊的运行。随着交通流量的不断增加，不仅会引起公路桥梁病害问题的发生，还会使其不断的发展恶化，达到不可控制的地步，严重影响路桥的使用寿命、人们的生命财产安全、交通的便利以及城市的形象。在路桥的养护管理过程中，存在很多的问题，如路桥项目的前期设计不合理、资金的缺乏、技术的落后、管理工作的不完备，都会使公路桥梁的使用年限受到影响，寿命极度缩短。所以，采取科学合理的措施，完善对公路桥梁的养护管理是十分必要的。
       路桥的养护工作对推动城市建设，提供人们便利出行以及保障人们的生命财产安全都起到很重要的作用。路桥养护工程需要紧跟时代发展，加大群众对路桥养护工作的重视程度，引进新型技术，加大监管力度，加大资金投入，保障我国路桥事业的健康发展。
