Experimental Study on Slurry Improvement and Gushing Control in Water-rich Silty Fine Sand Layers

[Objective] During EPB (earth pressure balance) shield tunneling through the water-rich silty fine sand layers, the ground is characterized by high friction, poor flow plasticity, and strong permeability. These features necessitate slurry improvement to enhance construction safety. [Method] Taking t...
