| Abstract: | Numerical simulation for a shield tunneling project has been made by three-dimension finite differential code for FLAC3D. Factors of a shield tunneling machine, pressures of grouting and soil chamber etc. have been considered in the simulation processing. Longitudinal variation law of soil and settlement curves are obtained; and compared with results of practice test. Results between the calculation and practice have a good agreeement. |
