摘要
北京轨道交通机场线二期(西延)北新桥站的附属结构毗邻既有5号线西南出入口,最小水平距离仅0.5 m。施工中采用调整施工顺序,超前注浆加固止水,背后回填注浆等措施,有效控制了结构变形和沉降。
The accessory structure of Beixinqiao station of Beijing capital airport rail transition line phase II(west extension)is adjacent to the southwest entrance of subway line 5 and the minimum horizontal distance between them is only 0.5 m.Some measures were adopted,such as adjustment of construction sequence,advanced grouting strengthening water-stopping and behind backfill grouting,etc.,to effectively control structure deformation and settlement.
