    Abstract:

    Under the geological conditions of soft and water rich sand, the shield receiving process is one of the major risks in shield tunneling. It is also one of the most difficulties in the whole work. Based on the shield receiving operations in the soft and water rich sand layer between Juyuanzhou Station and Hongwan Station of Fuzhou Metro Line 2, this paper expounds reinforcement of the shield receiving end, dewatering, control of the shield receiving attitude and secondary grouting, providing reference for shield tunneling in similar geological conditions in the future.
