摘要
通过对上跨铁路既有桥梁拆除施工支撑体系方案比选研究,采用抱箍支撑体系作为拆梁施工支撑平台,根据不同施工工况对抱箍支撑体系进行了力学特性分析,同时对既有桥墩进行了承载力评价。力学特性分析结果与实际监测数据表明,抱箍支撑体系安全可靠、确保了铁路运营安全。
Through the comparison and selection of the support system schemes for the demolition construction of existing bridges across the railway,the hoop support system is used as the support platform for the demolition construction.The mechanical characteristics of the hoop support system is analyzed according to different construction conditions,and the bearing capacity of the existing piers is evaluated.The analysis results of mechanical properties and the actual monitoring data show that the hoop support system is safe and reliable,which ensures the safety of railway operation.
