| Abstract: | Greater difficulties and requirement is unavoidable for the use of earth pressure balance shield machine in water-rich sand bed. The geological structure of the tunnel for Beijing subway line 6 Xincheng Station - Dongxiaoying Station] is the typical water-rich sand bed. Based on the successful case of earth balance shield tunneling construction, this paper concludes the improvement techniques for residue soil from water-rich bed and offers valuable experience for the similar construction afterward. |
