Experimental Study on Seismic Compression of Chinese Loess under Cyclic Direct Simple Shear Testing
Advances in Civil Engineering, 2022 Seismic compression is the accumulation of contractive volumetric strains in unsaturated soil from earthquake shaking. For Chinese loess, the behavior of seismic compression is extremely significant and has been recognized in historical earthquakes. As a

Dilatancy relation for overconsolidated clay [PDF]
, 2017 A distinct feature of overconsolidated (OC) clays is that their dilatancy behavior is dependent on the degree of overconsolidation. Typically, a heavily OC clay shows volume expansion, whereas a lightly OC clay exhibits volume contraction when subjected ...
