Undrained Behavior of Embankments on New Liskeard Varved Clay
The performance, including a failure, of two embankments in New Liskeard, Canada is analyzed. The underlying 150 ft. (45.8 m.) of medium to soft varved clay is studied with respect to stability, undrained deformations and excess pore pressure distribution. Total stress stability analyses were performed with undrained strengths based on measured and corrected field vane strengths, the average UC and UU strength and SHANSEP strength parameters with and without anisotropy. Effective stress analyses using pore pressures predicted from finite element analyses showed that either the effective stress strength parameters were much lower than those measured in the laboratory or the predicted pore pressures at failure were much too low. Undrained deformations and excess pore pressures at end of construction were predicted with the finite element program FEECON.
