承载力不足承台的加固设计研究

目前在桥梁结构的设计中,对桥梁承台研究不够,给桥梁结构的建设与运营留下了较多的安全隐患。该文从桥梁承台的一般设计理论与方法出发,采用撑系杆体系计算模式,对两座桥梁承台进行受力分析,并且针对承载能力严重不足的承台提出了预应力承台加固法及墩身加宽法,分别给出施工方案及适用范围,供相关工程技术人员参考。

Study on Reinforcing Design of Base Slab with Insufficient Bearing Capacity

It is scarce to study the base slab of bridge in the design of bridge structure,which remains many hidden troubles of the safety in the construction and operation of bridge structure. Starting from the general design theory and method of the bridge base slab and using the support bow string system calculation mode,the article analyzes the stress of two bridge base slabs,puts forward the prestressed base slab reinforcing method and the pier body widening method for the base slab because of seriously insufficient bearing capacity,and separately gives the construction scheme and the suitable range to give the reference for the relative engineering technical members.
