Can I read Pressure Gradients at The Tunnel Face of An EPB Shield on EtoBox?

Pressure Gradients at The Tunnel Face of An EPB Shield by Bob Moncrieff is a document available to read on EtoBox.

What is Pressure Gradients at The Tunnel Face of An EPB Shield about?

The document discusses pressure measurements taken during tunneling using an Earth Pressure Balance (EPB) tunnel boring machine (TBM). It found that the pressure gradients at the tunnel face differed from expectations and depended on factors like the rotation direction of the cutter head. Density measurements also indicated porosities higher than expected for the soil-water-foam mixture.
