Abstract
The invention disclosed includes a method of and apparatus for measuring the subsurface bearing strength of soil and the frictional resistance of the soil to movement of a pile through the soil. A probe is used for this purpose that includes two relatively movable members, an inner plunger with a flat face, and an outer tubular member. By measuring the forces imposed by the soil at different locations on the probe as the relatively movable members of the probe are moved through the soil the bearing capacity and the skin friction of the soil can be calculated.
