Immediate and Long-Term Behavior of the Evanston Tunnel in Chicago Clay
… are: undrained loading during tunneling in clay, non-radial pattern of the immediate displacement vectors, consolidation around the tunnel predominantly in the vertical direction, and long term groundwater infiltration toward the tunnel under constant phreatic surface. The time-dependent …

Pore Pressure Response and Ground Displacements in Chicago Clay During Tunneling and Over Long Term
The use of membrane influenced ground deformations around the tunnel mostly in the long term stage where it successfully (a) reduced dissipation rate of excavation-related excess pore pressure and thereby the rate of consolidation and (b) decreased both rate and magnitude of consolidation due to …

Lime treatment to improve frictional resistance and stability of stiff clay slopes
… of first-time or reactivated landslides in stiff clays and shales, permanent changes in the size and shape of clay particles must be realized to increase drained frictional resistance. Lime-soil reactions that may produce less platy and larger soil particles begin and continue with time under the …
