With the continuous development of China’s highway transportation industry, the number of highway bridge projects is also increasing, which greatly promotes the development of our country and facilitates the daily travel of our people. In the construction process of highway bridge, tunnel construction is often carried out. The construction of tunnel is very difficult, and the requirements for construction technology are also high, so it is easy to have various problems in the construction process.
   With the development and progress of society, the construction of modern highway and bridge in our country is developing rapidly, and the construction of highway tunnel is a very important project. In this regard, this book combines the current construction status of highway bridge tunnels in China, effectively improving the construction technology and quality management of road and bridge tunnels.
   Compared with other construction projects, highway and bridge construction is the main body of its management. Compared with other engineering construction, highway bridge engineering is relatively complex. On the basis of ensuring the progress of the project, we need to save the construction cost to the greatest extent, attach importance tothe construction management of highway and bridge, and put forward corresponding countermeasures to ensure the safe and effective construction of the project.

       社会的发展进步使得我国现代化的公路桥梁建设工程发展迅速，而公路隧道建设是一项十分关键的工程建设项目。对此，本书结合了当前我国公路桥梁隧道的施工现状，有效地完善道路桥梁隧道的施工工艺和质量管理工作。
       公路桥梁建设和其他建设项目比较而言有着很大差别，公路和桥梁是其管理的主体。与其他的工程建设相比公路桥梁工程相对复杂，在保证工程进度的基础上需要最大程度的节省建设成本， 重视公路桥梁施施工管理工作， 提出相应的解决对策，确保工程建设安全有效的进行。

Highway bridge is the throat of traffic artery, its operation status is related to economic development and people’s life. The research of highway and bridge maintenance management system has been more mature in many developed countries, but it is still in the development stage in China. The research of highway bridge maintenance management system is of great significance to ensure the scientific, reasonable and economic determination of maintenance countermeasures, prolong the service life of highway bridges, and ensure the safe operation of highway bridges.

   Highway bridge can provide basic guarantee for people’s safe travel, and it is an important transportation hub connecting various regions effectively, so it is necessary to pay more attention to its safety. With the continuous improvement of China’s social economy, highway and bridge construction plays an important role. However, the maintenance and reinforcement of highway bridges need to be strengthened in the process of use, which is an indispensable main method to increase the service time of highway bridges.

   China’s existing highway bridge construction has made great achievements, but most of the highway bridges have low design technical standards and poor traffic capacity, which can not meet the needs of transportation brought by rapid economic development, and the maintenance of old bridges will be in a peak period. The maintenance and management of highway bridges can not be separated from advanced concepts and technologies. At present, there are some problems in the maintenance concept of highway bridges, such as focusing on the construction of light maintenance, no distinction between road and bridge maintenance, unclear maintenance concept, indifferent crisis consciousness and lack of systematic concept; in terms of system, there is a lack of maintenance backbone team, the system is in form, and the management environment is not comprehensive; there are no perfect rules and regulations, and the technical understanding is not thorough; in terms of resources, the overall quality of human resources needs to be improved, maintenance funds are short, equipment is not complete, and timely maintenance information is lacking. In addition, there are also great deficiencies in the quality and safety of maintenance.

Since the reform and opening up, China’s construction industry has developed rapidly, and the scale of urban construction is expanding day by day. The development speed of cities and towns has become the standard to measure the modern civilization of a country and a region. After more than 30 years of hard work and practice, China’s modern architecture is developing towards high technology, high speed and high quality. China has made many major breakthroughs and new achievements in the field of construction technology. Some technologies have reached the world’s advanced level and become a big construction country in the world.

Engineering construction technology is the main element of construction engineering, and the level of engineering construction technology is directly related to the safety of the whole building. Due to the complex geological conditions, various foundation forms, different construction and management levels, and high concealment of foundation and foundation engineering, the construction of foundation and foundation engineering is more complex than that of superstructure, and it is easier to have quality hidden danger. A large number of facts have proved that the quality problems of construction engineering are mostly related to the quality of foundation and foundation engineering, so improving the level of construction technology is the most critical method to ensure the construction quality.
   Cost management serves the goal of project management. Project cost management is the basic work to manage the construction market by economic means. China’s project cost management is related to the reform and development of capital construction investment, construction industry and construction market, and is deeply affected by the system and policy. It can be seen that the project cost management has a very important position in the project construction.
