Webof sandy soils, liquefaction of gravelly soils is poorly understood and poses a risk to any Reclamation infrastructure founded on such soils (e.g, canals, levees, dams, power plants and other appurtenant structures). Testing gravelly soils is very challenging both in the lab and field, and this has contributed to the lack of knowledge. WebThe influences of dry density,initial confining stress and degree of liquefaction on the post-liquefaction shearing behaviour of gravelly soil were discussed,and the evolution of the micro-parameters of the granular system was also analysed.The results show that the stress-strain responses of gravelly soil after liquefaction can be divided into ...
