桥梁顶升技术在多跨简支板梁桥改造中的应用

Application of Bridge Jacking Technology in Reconstruction of Multi-span Simple-supported Slab Beam Bridge

摘要:

近年来，随着桥梁改造与维修项目逐渐增多，桥梁顶升技术不断改进和提升。结合多跨简支板梁桥顶升改造项目设计，重点给出对桥梁顶升技术方案中的关键问题及施工要点，并详细介绍了液压多点同步控制系统的工作流程，有关经验可供其他桥梁顶升项目参考。

Abstract:

Based on the engineering examples, the design and construction essentials of the jacking reconstruction project of multi-span simple-supported slab beam bridges are discussed. The related experience can provide the reference for the jacking projects of the other bridges.
