摘要
陆翔路-祁连山路贯通工程Ⅱ标段(K2+160.0~K3+265.15)是一项包含了顶管、基坑、桥梁、道路和排水的综合性工程,其北侧的路堤桥、基坑及部分顶管工程在运营轨交7号线及在建15号线50 m安全保护区内,距离7号线病害段最近距离6.1 m,距离15号线车站最近距离1.7 m。针对多个工况对临近轨交可能产生扰动的施工影响因素进行了分析,阐述了施工过程中针对这些影响所采取的保护性措施,并结合监测数据分析,总结施工过程中出现的问题和控制要点,给出了在轨交安全保护区施工的建议。
Luxiang Road-Qilianshan Road Link-up Project Section II(K2+160.0~K3+265.15)is a comprehensive project including the pipe jacking,foundation pit,bridge,road and drainage.The embankment bridge,foundation pit and partial pipe jacking works at it north side are all in 50-m safety protection areas of Metro Line 7 under operation and Metro Line 15 under construction,and are 6.1m from the nearest distance of the disease section of Metro Line 7 and are 1.7 m from the nearest distance of Metro Line 15 Station.The influencing factors of many construction conditions possibly on the adjacent rail traffics are analyzed.The protective measures taken for these influencing factors in the construction are set forth.Combined with the analysis of monitoring data,the existing problems and the control essentials in the construction are summarized.The suggestions for the safety protection area of rail traffic are given.
