摘　　要：中远两湾城(一期)B14基坑采用锚喷网(工钉)支护法获得成功。施工中通过动态监测反馈到施工 过程,及时调整支护参数;对于深五米以上地段增加了竖向注浆锚管以防止深部滑移;最大限度地 缩短各分层的支护施工时间,从而有效控制各阶段边壁的变形,确保基坑边壁整体稳定。同时对基 坑内进行轻型井点抽水和明排水,以保持施工作业过程的干燥。This paper describes successful using Anchoring - Shotcreting - wiring (earth pin)support system at Zhongyuan Two Loches Chateau (first phase) B14 faudation pit.Under conctruction dynamic measuration feedbacks to process of construction and ill be adjusted timely. Under five meter depth, the vertical anchor tube of infuse slurry was increased to prevent the deep slippage. It furthest curtails each layered time of supporting construction, thereby to control available distortion of ach layered side wall, and insures the whole stabilization of foudation pit. Meanwhile it does light - well point pump water and open - drainage in foudation pit to preserve desiccation in construction process.
