Table 1 gives data from a standard shearbox(direct shear) test on a sample of 125g of dry
sand. The initial dimensions of the sample were 60mmx60mm on plan x20mm in height. The
test was caried out at a constant normal effective stress of 50k:Pa. Take the specific gravity
of the soil grains Gs=2.65. Plot graphs of
(a) shear stress t against shear strain y;
(b) volumetric strain evol against shear strain y;
(c) specific vohume v against shear strain y.
(d) Comment on these graphs and estimate the peak and critical state effective angles of
friction of the soil.
