PLATE LOAD TEST KIT

Complete system for determining the bearing capacity of the soil in compliance with the reference standards

Plate Load test is usually used for the verification of the bearing capacity of the land of the substrate, of the foundation layer and the base layer of the flooring, although it is not uncommon to its use to investigate the bearing capacity of the soil surface or to the state compaction of granular materials and road surfaces.

The test consists in transmitting to the soil to be tested and the subsequent increasing load increments, detecting simultaneously the sagging and therefore allows to directly determine a form of deformation or compressibility of the soil. The load transmission takes place via the application of a force by means of a hydraulic system of thrust, of a circular plate. The subsidence induced by the ground plate are simultaneously detected by centesimal or digital data acquisition systems, integral with a frame of reference outside the area of influence of the applied load. Of fundamental importance, in any case, is the use of the proper contrast medium whose mass is a function of the expected load.

These tests are generally conducted with metal plates of standard diameter fro 300 to 760 millimeters, could be carried out from ground level and inside the wells whose depth is limited only by the size of the jack and related extensions.

Standards: CNR BU 146, SN 670 317 and 670317th, the LCPC method CT2.
