摘　　要：以上海北横通道盾构穿越运营中的轨道交通案例为背景,提出超大直径盾构近距离穿越运营中轨道交通施工技术,并采用轨交10号线隧道结构沉降监测数据验证穿越施工技术的可行性。轨道交通隧道结构竖向位移原位监测数据表明,超大直径盾构近距离穿越运营中轨道交通的施工技术满足被穿越既有地铁隧道的变形控制要求,该穿越施工技术可为沿海软土地区相似工况条件下盾构近距离穿越运营中轨道交通线路提供施工借鉴。Based on the case of Shanghai Beiheng Passage with shield passing through the rail transit in operation,the construction technology of ultra-large diameter shield passing through the rail transit in operation in short distance is proposed,and the feasibility of the construction technology is verified by using the monitoring data of tunnel structure settlement of Rail Transit Line 10.The in-situ monitoring data of the vertical displacement of the rail transit tunnel structure show that the construction technology of the super-large diameter shield passing through the rail transit in operation in a short distance meets the deformation control requirements of the existing subway tunnel.This construction technology can provide a reference for the construction of shield passing through the rail transit in operation in a short distance under similar working conditions in coastal soft soil areas.
