预应力技术在公路桥梁工程施工中的应用

Application of Prestressed Technology in Highway Bridge Construction

当前我国很多地区在公路建设中采用的仍然是比较落后的管理方式,导致公路施工中效率和质量都比较低,影响了工程建设的进度、质量、成本、使用效果等。此外,很多地区存在软土等不良地质,导致公路桥梁施工面临严重的质量问题,文章针对预应力技术的应用及公路桥梁施工保障展开探讨。分析公路工程常见风险原因,如软土地基施工安全等。从混凝土预应力技术分析,多跨连续工程中预应力应用分析等方面阐述预应力技术应用。

At present,many areas in China are still lagging behind in highway construction management,resulting in low efficiency and quality of road construction,affecting the progress of construction,quality,cost,the use of results.In addition,there are some poor geological conditions,such as soft soil,which lead to serious quality problems in highway bridge construction.Therefore,the application of prestressing technology and highway bridge construction guarantee are discussed. Analysis of highway engineering common risk reasons, such as soft soil foundation construction safety. From the concrete prestressed technology analysis, multi-span continuous engineering prestressed application analysis and other aspects of the application of prestressed technology.
