A simplified full-depth precast concrete deck panel system for accelerating bridge construction (ABC) is introduced and a finite dement analysis (FEA) is con- ducted to investigate the static and dynamic responses of this conceptual deck system. The FEA results are compared to those of the traditional full-depth precast concrete deck panel system. The comparison results show that the mechanical behavior of the new deck system is different from that of the traditional deck system. The concrete decks in the new system act as two-way slabs, instead of the one-way slab in the traditional system. Meanwhile, the connections in both the longitudinal and transverse direc- tions may need to accommodate the negative moments. Compared to those in the traditional system, the longitu- dinal nominal stress at middle span increases a lot in the new deck system and the effective flange width varies significantly. In addition, the dynamic results show that the impact factor is influenced by the spacing of connections. Finally, some design concerns of the new deck system are proposed. 展开更多

At present, some achievements have been made in the research of subgrade settlement in China, and the main research achievements are the optimization schemes for the problems such as bumping at bridge head during the use of roads and bridges. For the construction of subgrade in transition section, the construction process and materials used can have a certain impact on the quality and safety performance of road and bridge. The harm brought by uneven subgrade is mainly that it is easy to form icing and water accumulation in rainy and snowy weather, which leads to out-of-control of vehicles and affects the driving safety of vehicles. Therefore, in order to improve and optimize the above problems, in the construction process, it is necessary to eliminate the factors that lead to uneven settlement of subgrade in a variety of ways to improve the safety and economic value of roads and bridges. 展开更多

It is very important to ensure the quality of highway bridge construction and do a good job in soft soil foundation treatment. Only by effectively controlling the overall quality of soft soil foundation treatment can the stability and reliability of highway bridge structure be effectively controlled and the smooth development of highway bridge construction activities be promoted as a whole. In highway and bridge construction activities, the treatment of soft soil foundation is the key. Only by doing a good job in the treatment of soft soil foundation can the service life of the project be effectively prolonged. If the soft soil foundation is not treated, it will cause problems such as road bridge subgrade subsidence and cracks. Only by ensuring the overall quality of subgrade treatment can a solid foundation be laid for the quality control of actual road bridge construction activities. 展开更多

With the continuous development of social economy, China's highway and bridge construction has also made significant achievements. At the same time, there are more and more highway vehicles, which brings certain challenges and difficulties to the operation process of highway and bridge. In highway bridge engineering, there are many types of highway bridges, and the construction difficulties of different types of bridges are different. When the highway bridge is open to traffic for a period of time, with the continuous influence of traffic load, coupled with the interference of climatic environment, human factors and other conditions, diseases will inevitably occur in various structures of the highway bridge, and the bearing capacity of the bridge will gradually decrease over a long period of time, affecting the safety and stability of the highway bridge project. Therefore, it is necessary to carry out the necessary testing for the insufficient bearing capacity of the highway bridge and formulate effective reinforcement measures. In this paper, a series of reinforcement measures are proposed to solve the related problems of insufficient bearing capacity of highway bridges and are applied in specific projects. 展开更多

In recent years, with the rapid development of China's economy and the acceleration of the urbanization process, the demand for infrastructure construction has become higher and higher, thus ensuring the sustainable development of the national economy and the circulation of commodities. Therefore, the construction quality of soft foundation is an important factor affecting the quality of highway bridge engineering in our country. Soft foundation is an important potential safety hazard in highway and bridge construction. Its water content is above 70%, and it has low foundation bearing capacity, permeability, compressibility, viscosity and other characteristics. If not paid attention to in the construction process, it will not only affect the overall use effect of the project, but also cause uneven settlement, instability, collapse and other problems, causing serious consequences. Therefore, it is necessary to adopt appropriate technical measures in highway, bridge and other projects. Therefore, in highway bridge construction, technical personnel should strengthen the control of the soft soil foundation in time, understand the influence of the current soft soil foundation on the bridge structure from the perspective of soft soil foundation treatment, fully understand the engineering requirements, and master the technical key points of construction at the same time, improve the construction treatment technology of the soft soil foundation of the road bridge, and guarantee the construction quality. In order to further improve the quality of highway and bridge construction, the feasibility analysis scheme of soft foundation reinforcement technology is formulated. Based on the characteristics of soft foundation and the problems in construction technology, this paper discusses its specific application. 展开更多
