WebJul 19, 2024 · The critical state line and isotropic consolidation line on the loosest state of silica sand no. 5 were curved in the e−logp′ plane but straightened in the e − p′ α=0.7 plane. In the e − p′ α=0.7 plane, a reasonable linear critical state line of silica sand no. 5 was proposed by adjusting it to match the isotropic consolidation ... WebWhile laboratory testing has been used to estimate the steady state shear strength of soils (discussed in Chapter 2), such testing generally is viewed as unable to replicate the residual shear strength of liquefiable soil in situ (NRC, 1985; Seed, 1987; Stark et al., 1999). The steady state shear strength is a measure of the post-triggering ...
