已通车城市互通匝道支座脱空原因分析及加固处理

Cause Analysis and Reinforcement Treatment of the Support Void of Urban Interchange Ramp

在我国铁路、市政以及公路桥梁的施工建设中,互通匝道的施工已经非常普遍。与此同时,在城市互通匝道的施工过程中,支座脱空问题也成为最常出现的质量问题之一。基于此,本文重点结合实际工程案例,针对已通车城市互通匝道支座脱空原因进行了详细的分析,并有针对性的提出了加固处理措施,以供参考。

In the construction of railway,municipal and highway bridges in China,the construction of interchange ramp has been very common.At the same time,in the construction process of urban interchange ramp,the problem of bearing emptying has become the most common quality problem.Based on this,this paper focuses on the actual engineering cases,for the urban interchange ramp support has been opened to the reasons for the detailed analysis,and targeted reinforcement measures for reference.
