Numerical model of surface subsidence during subway tunneling

Results are presented for modeling of surface subsidence resulting from boring operations for construction of the U-8-Nord subway line in Munich. Measurements of surface subsidence on completion of tunneling operations served as verification for the model. A soil-behavior model, describing most reli...

Description
Summary:Results are presented for modeling of surface subsidence resulting from boring operations for construction of the U-8-Nord subway line in Munich. Measurements of surface subsidence on completion of tunneling operations served as verification for the model. A soil-behavior model, describing most reliably the subsidence of the ground surface during tunneling was selected. Factors controlling surface subsidence were determined.
