S+t,

Sensitivity of soil, equals ratio of

remolded to undisturbed shear

strength.

s

stress or condition in situ, used

instead of strengh parameters c and

[phi].

construction in consolidation

analysis for gradual loading.

T+v,

Time factor in consolidation

analysis for instantaneous load

application.

tsf

t,t+1,,

Time intervals from start of loading

t+2,,t+n,

to the points 1, 2, or n.

t+50,,t+100,
