摘要: 在桥梁墩柱附近设置限位装置是桥梁顶升施工中的重要安全措施之一。然而受桥梁结构和墩柱布置的影响,实际限位装置的设置受到限制。本文结合实际工程顶升施工中的限位防护体系的设计,开展了相应的设计优化,并进行了安全性承载力分析,保证了背景工程的顶升施工安全。
Abstract: The installation of block protection system near the bridge pier is one of the most important safety precautions in the construction of bridge lifting construction. However, due to the influence of the structure of the bridges and arrangement of the piers, the setting of the protection system is difficult to carry out. In this paper, the optimized design based on the protection system in the lifting construction of the actual project is carried out and the safety bearing capacity is analyzed, which ensured the construction safety of the actual project.
