报告简介： 

The success of a TBM drive depends on understanding the interaction between the TBM and the soft soil. In this seminar we will follow the TBM as it moves through the soil:

- The interaction with soil in front of the TBM is important for the stability of the tunnel face both in a slurry shield and in an EPB and influences the properties of the soil in the mixing chamber and in the screw conveyor.

- Sealing of the front face during stand still is for a slurry shield determined by the plastering properties of the slurry. These are influenced by the excavated soil.

- The interaction between the TBM shield and the soil is important for the loading on the tail of the TBM.

- The pressure distribution during tail void grouting determines the loading on the lining and the pressure distribution next to the lining in the soil.

The lectures will combine the results of field tests and laboratory tests with theory.
