... mechanics terms; in fine soils it is groundwater pressures which cause the problem, and the flowrate is almost irrelevant. A successful groundwater control system would stabilize the excavation by porewater pressure reduction (or pore pressure control) and not by literally dewatering the soil. However...

... Vaults Conclusion 49. The reduction of building damage in highly developed areas like London can make a major contribution to the success of a tunnelling project. Consequently, accuracy of prediction is very important. A simple and accurate model has been found, capable of predicting subsurface ground...
