与传统的道路桥梁施工技术相比,预应力可提高施工材料科学、合理的使用水平,降低混凝土结构梁在竖向上的剪力及结构所承受的主拉应力,且预应力技术安装简单,可提高施工效率,因此在道路桥梁施工过程中,预应力技术的应用十分广泛。但是受施工人员、施工技术等因素的影响,预应力技术的实际应用还存在一定问题。讨论道路桥梁施工中预应力的问题,并采取有效的解决策略,可进一步提高工程施工质量。
Compared with the traditional road and bridge construction technology, prestressing can improve the scientific and reasonable use of construction materials, reduce the vertical shear force and the main tensile stress of the structure, and the prestressed technology is easy to install. Improve construction efficiency, so in the process of road and bridge construction, prestressed technology is widely used. However, due to the influence of construction personnel, construction technology and other factors, the practical application of prestressing technology still has some problems. Discuss the problem of prestress in the construction of road and bridge, and take effective strategy to solve it, which can further improve the construction quality.
