RISNumerical Examination of EPB Shield Tunneling–Induced Responses at Various Discharge Ratios
Publisher: American Society of Civil Engineers
Abstract: This study investigated earth pressure balance (EPB) shield tunneling–induced responses in terms of muck pressure, machine parameters, and surface settlements using an efficient numerical scheme that couples PFC3D and ...

Stress Responses Associated with Earth Pressure Balance Shield Tunneling in Dry Granular Ground Using the Discrete-Element Method
Publisher: American Society of Civil Engineers
Abstract: This study investigates stress responses associated with earth pressure balance (EPB) shield tunneling in dry granular ground. A numerical model using the discrete-element method (DEM) was employed to simulate both the ...
A Unified Analytical Model for Undrained Compressibility Behavior of Foam-Conditioned Coarse-Grained Soils Based on Effective Stress Analysis
Publisher: ASCE
Abstract: During the tunneling process of earth pressure balance (EPB) shield machines, the undrained compressibility of foam-conditioned soils in the excavation chamber is essential for reducing the fluctuation of chamber pressure ...
A Novel Index to Evaluate the Workability of Conditioned Coarse-Grained Soil for EPB Shield Tunnelling
Publisher: ASCE
Abstract: Although slump testing has been used extensively to assess the workability of conditioned soil in shield-driven tunnelling, this traditional evaluation method still requires many subjective descriptions. This study developed ...
