摘要
北京地铁16号线区间下穿既有9号线结构,采取多项措施进行综合控制,通过对既有线实时动态监测,严格各道施工工序衔接,加强过程措施实施,在非降水条件下顺利地完成了长距离穿越,确保了既有结构变形在允许变形控制值范围内。
Beijing subway line 16 interval passes through under the structure of line 9,and many measures were adopted for general control,such as real-time dynamic monitoring on existing subway line,strict management of connection among different construction steps and effective implementation of process measures,etc.,to successfully realize long-distance passing through without dewatering and to keep the deformation of existing structure within the allowable scope.
