Geotechnics

A test designed to determine the allowable pressure on the subsoil. The adopted criterion is either that of stopping this stress using a method determined by experiment, or that of conventional fixing of the allowable pressure.

The test must be carried out at the same depth as the future foundation. The surface on which the bearing plate sits must be freshly stripped, and neither modified nor tamped. As much as possible, the test must be continued until the ground breaks. Loading must be progressive by fractions of a tenth of the presumed breaking load; every new loading can only be executed after stabilisation under the previous load. Readings are on flexigraphs; these different readings are transferred to a graph and show the curve of the sinking. The test finishes when the breaking of the ground is observed (an immediate and great increase in sinking) or after stabilisation under the last load as long as the total subsidence is at least equal to a tenth of the diameter or side of the plate, without exceeding six times the pressure of the use which is expected during the project. The table is unloaded without omitting...
