Apr 30, 2018 Let x be the depth below the upper point of the cone, and let ##theta## be half the included angle of the cone. The pressure at depth x is ##p=rho g x##. Since the pressure is acting perpendicular to the sloped sides of the cone, the downward component of the pressure force acting on the side is ##psin{theta}=rho g x sin{theta}##.

The density of the undisturbed or compacted soil in situ is determined by the sand-cone method (ASTM D 1556 2007 or AASHTO T 191 2013), the rubber balloon method (ASTM D 2167 2008) or nuclear methods (ASTM D 5195 2008 or AASHTO T 310 2013). All three methods are outlined in Section 1.11. This method is simpler than the sand-cone
