Preface

Highway bridge plays a very important role in urban transportation, which strengthens the communication and exchange between cities, and has become the actual needs of modern economic development. The safety of highway bridges is an important factor affecting the development of transportation. In order to better improve the quality and safety of highway bridges, it is necessary to strengthen the supervision of the construction process of highway bridges and the maintenance after putting into use, so as to effectively ensure the construction safety and use safety of highway bridges, and make the highway bridges give full play to their important value.
      According to the construction environment of highway bridge engineering, considering the influence of geographical environment and climate, scientific and reasonable construction design is carried out. We should strengthen the construction management and improve the relevant construction technology to ensure the smooth progress of the project under the environmental conditions and avoid the impact of environmental factors on the quality of the project. Bad weather and natural disasters will have a certain impact on the quality of highway bridges. In the design of highway bridges, we should consider the resistance of highway bridges to environmental factors after they are put into use. In the maintenance of highway bridges, it is also necessary to take effective protective measures against a variety of environmental factors to improve the safety and stability of highway bridges. The rapid development of highway and bridge construction in China has laid a solid foundation for the rapid development of China’s economy. But in its construction technology and maintenance program, there are still deficiencies, which have a certain impact on the quality of highway bridges. How to do a good job in the construction technology and maintenance scheme of highway and bridge engineering is one of the problems to be solved by relevant enterprises.

前 言

公路桥梁在城市交通运输当中起到了极为重要的作用，加强了城市间的沟通与交流，已经成为现代经济发展的实际需要。公路桥梁的安全问题，是影响交通运输发展的重要因素。为了更好的提升公路桥梁的质量安全，需要对公路桥梁工程的施工过程的监管以及投入使用后的养护加强管理，以有效地保证公路桥梁上的施工安
全和使用安全，使公路桥梁充分发挥其重要的价值。
        根据公路桥梁工程的施工建设环境，考虑到地理环境和气候的影响，进行科学合理的施工设计。加强施工管理，对相关施工技术进行改进和完善，以保证在该环境条件下工程能够顺利进行，避免由于环境因素而对工程质量造成影响。恶劣天气以及自然灾害会对公路桥梁的质量造成一定的影响，在公路桥梁的设计当中，要考虑到公路桥梁在投入使用后对于环境因素影响的抵抗能力。在公路桥梁的养护方面，也需要针对多种环境因素进行有效的防护措施，以提高公路桥梁更加安全稳固。
        我国的公路桥梁建设得到快速发展，为我国经济高速发展打下了坚实的基础。但是在其施工技术与养护方案上，仍然存在着不足，这样就对公路桥梁的质量产生了一定的影响。如何才能从根本上将公路桥梁工程的施工技术与养护方案工作做好，是相关企业亟待解决的问题之一。
