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.

改革开放以来,我国建筑业发展很快,城镇建设规模日益扩大,城镇的发展速度已成为衡量一个国家和地区现代文明的标准。 经过最近 30 多年的努力实践, 我国的现代化建筑正朝着高技术、快速度、高质量方向发展,我国在建筑工程施工技术领域取得了许多重大突破和新的成果,有的技术已经达到世界先进水平,成为世界建筑大国。
工程施工技术是建筑工程的主要要素,工程施工技术的水平直接关系到整个建筑物的安全。由于我国地质条件复杂,基础形式多样,施工及管理水平存在差异,同时地基与基础工程具有高度隐蔽性,从而使得地基与基础工程的施工比上部结构更为复杂,更容易存在质量隐患。大量事实证明,建筑工程质量问题多与地基与基础工程质量有关,因此提高施工技术水平是保证施工质量最为关键的方法。
造价管理是为工程建设项目管理的目标服务的。工程造价管理是用经济手段管理建筑市场的基础工作。我国工程造价的管理是与基本建设投资、建筑业、建筑市场的改革与发展关联的,深受体制与政策影响。由此可以看出,工程造价管理在工程建设中具有极为重要的地位。
Highway is an important infrastructure for the development of national economy. It is the most flexible mode of transportation in the whole transportation system. It has the characteristics of direct, rapid, convenient and strong adaptability. With the rapid development of China’s transportation, especially the emergence of a large number of high-grade highways, highway transportation plays an extremely important role in the national political, economic, cultural and military construction.
Expressway is an engineering structure that provides safe, fast, comfortable and economic services for vehicles and other means of transportation. After it is completed and put into use, it will suffer the repeated wear and impact of wheels and the erosion of rainstorm, flood, wind sand, ice and snow, sunlight, freeze-thaw and other natural forces, as well as some defects left in the design and construction, which will inevitably lead to the deterioration of road use function and driving service quality, and even the interruption of traffic. In order to extend the service cycle of expressway, ensure smooth flow, minimize and avoid the loss to highway users due to the above reasons, in order to adapt to the new situation of increasing traffic volume and heavy vehicles, we must take appropriate engineering and technical measures, adhere to daily maintenance, and timely repair the damaged parts in accordance with the principle of “prevention first and prevention combined”. We also need to keep the highway in good condition, smooth, clean and beautiful, carry out preventive large and medium-sized maintenance periodically, gradually change the general technical conditions, and improve the use quality and disaster resistance ability of the highway. Therefore, highway maintenance is a regular work to ensure high-speed, safe and comfortable driving. It is of great significance to strengthen highway maintenance, repair and improvement.
