| Abstract: | The similarity formulae of model testing in advancing shield tunnels are proposed based on the Goodierian theory. Many practical factors such as the advancing pressure and speed, the soil pressure, the soil discharging and losing ratio, and the infused mud quantities are included in them. The viscosity-elasticityplasticity property as well as the large deformation of the soft soil are considered in the discussion. The formulae can be used to design the testing model and to process the testing data. |
