真空压降技术在预应力砼桥梁施工中的应用

摘要

结合厦门市东安大桥的工程实例介绍了真空压降技术的原理和真空压浆技术负压值的确定，其次重点说明了真空压降技术的施工过程、施工注意事项和施工质量控制措施，最后阐述了真空压降技术相对传统压降技术的优点和其带来的经济效益。%　　Combined with Dongan Bridge Projects in Xiamen, the principle and determining negative pressure value of vacuum grouting technology are introduced. The construction process, construction considerations and construction quality control measures of vacuum grouting technology are illustrated. The advantage and economic benefits of vacuum grouting technology compared to the traditional technique are introduced.
