Feasibility of Face Surcharging during Deep Settlement-Free Tunneling in Dense Urban Settings
Abstract A procedure is proposed for the computational modeling of the driving of a deep tunnel by a tunnel-boring machine (TBM) with an active surcharge on the face, which is realized in the “GEO-MIGG” program. Basic factors affecting the stress-strain state (SSS) of the “soil bed-TBM- buildings and structures of the urban setting” system are demonstrated in a trial example. The feasibility of using the proposed procedure is confirmed by comparing results of computational modeling of a practical example of tunneling for the third transportation beltway around Moscow in the area of Lefortovo using a TBM manufactured by the German firm Herrenknecht” with data derived from field observations.
