In order to determine the consistency or nature of soil or sub-soil, or to be able to classify the soil or sub-soil, the permeability of the soil or sub-soil layers under examination is measured. This is done by measuring, as the key parameter, the degree of consolidation or so-called pore-water over pressure. To this end, the invention calls for the use of a penetrator (1) with a measurement probe which has a flattened tip (16, 21). |
