How would you explain, conceptually, to a "non-geotechnically" trained civil engineer what occurs in saturated soils at the boundary between dense (non-cohesive AND non-liquefaction prone) soils; over, looser (non-cohesive) soils that are susceptible to liquefaction?
For example:
-what keeps a dense cohesion-less layer from simply collapsing into the liquefaction prone layer during a major seismic event?
-are there degrees of liquefaction? Will the soils near the water table be "less" liquid like and support the mass of soils above it?
Any comments or thoughts would be appreciated.
No buildings involved, just a mental exercise.
Thanks
