Abstract

[automatically translated] The purpose of this work is to perform the geo-referenced detection of physical-mechanical characteristics of the soil (penetration resistance, index of the relative state of compaction, and normal shear stress to the ground level, required for working the soil through the use of a subsoiler) in a field of inland Sicily, along parallel trajectories to those already covered by a tractor system - plow during plowing done five years before the tests themselves. The resistance to penetration detection system consists of a load cell, connected to a rod of penetration, which ends with the relative cone and is installed on a frame, fixed before to a crawler tractor. The shear stress detection system consists of a load cell, installed on the tractor hitch, connected to the subsoiler. Both the load cells and a DGPS mobile receiver, installed on said tractor, are connected to a data acquisition system suitably developed. This system consists of a multi-channel data acquisition card and a software specifically developed in LabView environment and installed in a portable PC. Further tests will be performed in the same plot, in the presence of a moisture content different from that of the present work, in order to verify the influence of this variable on the resistance to penetration of the soil and on the normal shear stress to the ground level. They are connected to a suitably developed data acquisition system. This system consists of a multi-channel data acquisition card and a software specifically developed in LabView environment and installed in a portable PC. Further tests will be performed in the same plot, in the presence of a moisture content different from that of the present work, in order to verify the influence of this variable on the resistance to penetration of the soil and on the normal shear stress to the ground level.
