According to the TA02 Part of No.10 Line of Nanjing subway,the paper adopts some measures,including the frozen consolidated body,the tunneling in wate,the simultaneous and secondary grouting,and the supervision and measurement,so as to ensure the difficulties in the safety progress of the shield in the sandy stratum,solves some construction difficulties,including the flowing sand,the leaking,and the extra excavation in the sandy soil layer,and proves by the construction application that the technique can control the settlement and upheavals of the surface effectively,so the shield can be constructed safely.
