Abstract:

The prediction and control of ground deformation and displacement resulted from large slurry shield tunneling in complicated environment are important problems to be solved. Combined with Shanghai Yangtze River Tunnel Project, the ground settlement data of test section approach to building areas in uplink tunneling is analyzed. The ground surface movement of test section induced by single tunnel excavation as well as cumulative movement due to two parallel tunnel excavation is accurately predicted by using stochastic medium theory. Based on ground movement prediction, recommended procedures for tunneling in a building areas are presented. The case study shows that the prediction method and measures presented for ground movement control are reasonable and reliable and have some practical value.

Key words: large slurry shield, ground deformation and displacement, stochastic medium theory, building
