Liquefaction of Highly Saturated Sand Layer under Oscillating Water Pressure [PDF]
, 1982 In this paper the vertical distribution of pore water pressure in the highly saturated sand layer under the oscillating water pressure are treated theoretically and experimentally. By the experiments it is shown that the water pressure acting on the sand

Calculating the state parameter in crushable sands [PDF]
, 2019 The state parameter (y) measures the distance from the current state to the critical state line (CSL) in the compression plane. The existence of a correlation between both the peak angle of shearing resistance ( # $ ) and peak dilatancy and y is central ...

A new slurry-based method of preparation of specimens of sand containing fines [PDF]
, 2007 A new method of specimen reconstitution is presented that is appropriate for element testing of sands containing either plastic or nonplastic fines. The method allows reconstitution of homogeneous, saturated specimens of sands containing fines whose ...

Evaluation of Liquefaction Resistance by In-situ Testing and Its Application to Reliability Design [PDF]
, 2000 A calculation method of probability of liquefaction is proposed in this paper. The spatial variability of soil parameters for the dynamic shear strength, i.e., N-values, median grain size, fines contents, and the statistical characteristics of the ...
