摘要
随着我国城市轨道交通建设的不断推进和发展,邻接既有地铁线路和车站进行施工的情况已经无法避免,然而后建车站的深基坑开挖施工将对既有轨道交通结构产生附加应力和变形,从而对其带来不利影响。结合工程实际,总结施工技术,叙述了临近既有线的换乘站土方开挖及爆破施工中所运用的技术和经验,数据资料可为今后其他类似项目的施工提供参考与借鉴。
With the continuous advancement and development of urban rail transit construction in China,it is inevitable to carry out construction adjacent to the existing subway lines and stations.However,the deep foundation pit excavation of the later stations will produce additional stress and deformation to the existing rail transit structure,which will bring adverse effects on it.Combined with the actual engineering,the construction technology and describes the technology and experience used in earthwork excavation and blasting construction of the transfer station near the existing line.The data can provide reference for the construction of other similar projects in the future.
