Abstract

The large diameter slurry shield receiving end of Nanjing subway river-crossing tunnel in subway line No. 10 is water-rich sandy soil. The most appropriate way of reinforcement for the poor geological conditions were selected as follows: cement mixing pile-triaxial pressure rotary freezing spray pile-vertical consolidation, and the key technology and main points of large slurry shield water receiving were analyzed and summarized. The surface subsidence of the vertical frozen shield construction during receiving was investigated in situ test by adopting the combination of engineering application and actual research methods, and the vertical development rule of the temperature of the frozen soil wall was analyzed for judging whether the vertical frozen soil wall thickness and average temperature meet the requirements of shield to receive, and the time of getting rid portal was determined. Receiving end surface subsidence results showed that the land surface subsidence of the strengthening regional for the shield receiving is less than 4.6 mm, and we can draw a conclusion that the effect of the foundation reinforcement treatment is good. The water receiving technology can guarantee the rich sand layer security to receive large shield, and can provide important technical reference for future similar large shield receiving by this project research.
