System for 'in situ' measurement of shear strength and the frictional force in soils.

摘要

System for "in situ" measurement of shear strength and the frictional force in soils.; The system defines a team to find out the resistance that the ground offers when cut, and the frictional force per unit area exerted by the ground on blades (4) and (5) mounted on a frame (1), cutting each blade (4) at different depths, allowing simultaneously measure the shear force at different levels of depth. The cutting blades (4) and friction (5) located behind those, are mounted through a system of articulated quadrilateral formed by pairs of vertical rods (9) on both sides of the blades (4) and (5 ), so that in combination with a load cell associated with each blade (4 or 5), it is possible to separately make the cutting resistance and the frictional force of the ground.
