... by a relatively complicated system of integral and non-linear differential equations. Some analytical solutions of these mathematical models are already available (Spence & Sharp, 1985; Savitski & Detournay, 1999; Garagash, 2000; Savitski, 2000; Adachi, 2001; Adachi et al., 2001). However, these solutions...

... of the rate from field observations and case studies may not be unreasonable. In this study, an inverse-hyperbolic function of time is employed to model this strength reduction (Yoshida and Adachi, 1992). Depressed pore water pressure develops in ground upon excavation, then the pore water pressure...
