mixture of sand and silt on the state lines of experiments using periodic s·hmhvry

mas·hyy saturated soil liquefaction during earthquakes, shnakhthshdhyy phenomenon that many researchers in the past three decades has attracted. more research on the liquefaction of saturated soils has focused mas·hyy the natural soils are rarely composed of clean sands, and mixed with clay or silt soils, which is why the study has important ghyrkhmyry and paste. despite numerous studies on these soils are still many aspects of the behavior of these soils is unknown. in this study the effect of shear stress to strengthening and dissimilar behavior mas·hyy soils mixed with different percentages of silt is ghyrkhmyry. the results of 67 experiments carried out so that the periodic s·hmhvry demonstrates that the change in the initial phase angle) iptl in the $ q-p '$ is strongly influenced by the degree of back tension. the percentage of fine soil mixed with similar or dissimilar soils, and consolidate the changes clearly on the line in the initial phase of the $ q-p '$ is effective.
