公路工程道桥施工中预应力施工技术的应用分析

Application Analysis of Prestressed Construction Technology in Highway Engineering Road and Bridge Construction

在公路工程路桥施工过程中,预应力技术由于其较好的受力性能能够大幅度提高公路工程的安全性和稳定性,而且该技术的应用也可减轻工件自身重量,这不仅避免了材料的浪费,而且使工件的安装工作更加便捷。现阶段,我国在公路工程路桥施工中应用预应力技术虽然已经拥有了相对完善的体系,但是由于我国在预应力技术的应用方面仍处于起步阶段,因此仍存在一些问题,如在使用预应力技术的过程中会出现裂缝现象,该类问题是现阶段亟需研究和解决的关键问题,其关乎着整个公路工程路桥施工的发展前景。

During the construction of roads and bridges in highway engineering,the prestressing technology can greatly improve the safety and stability of highway engineering due to its better mechanical performance,and the application of this technology can also reduce the weight of the workpiece itself,which not only avoids the material It is wasteful and makes the installation of the workpiece more convenient.At this stage,although China has a relatively complete system for the application of prestressing technology in the construction of roads and bridges in highway engineering,there are still some problems,such as the use of prestressing technology,as the application of prestressing technology is still in its infancy in China.There will be cracks in the process.This kind of problems is a key problem that needs to be researched and solved urgently at this stage.It is related to the development prospects of road and bridge construction of the entire highway engineering.
