The program of soil inestigation must be suitable to the size of the problem and the nature of the terrain, with a weighted compromise between technical and economic requirements With the growing importance and the sensitivity of to achieve, and increasing the complexity of the geotechnical problem you justify investigations increasingly accurate. The impact on total spending is small when compared to the benefits which may arise and avoid planning too cautious or otherwise more costly safeguard from incorrect assumptions of the calculation. E'quindi clear that in geognostic investigations assume a role of fundamental and decisive importance for the resolution of problems.
In general terms, the primary objectives of an investigation geognostic are aimed at determining:
- The stratigraphy of the subsoil
- Of its main physico-mechanical
The experimental methods available are many and must be programmed each time, based on the specific terms of the problem Among the on-site investigation is first of all, polls penetrometers tests with static and dynamic, able to provide information (with vertical continuity) for a good determination of the parameters of the soil. In addition to these traditional methods of research.
Ital Sonda has developed new and revolutionary methods of data acquisition through the use of destruction of a drilling core with drilling equipment. With this system may start more in-depth studies of the physical properties of the soil using mechanical tests scissometrics, dilatometer, pressiometriche and load plate. Regarding the hydraulic characteristics can be tested by direct evidence or micropermeability. Indirect measures of a geophysical, finally, to assess possible forms of land cutting through th determination of the speed of seismic waves.
Among the laboratory investigations, Ital Sonda uses the most comprehensive and sophisticated laboratories of the Italian territory by adding the most common classification of evidence (proof size, density and consistency) tests for determining the mechanical characteristics (tests edometriche of compression and shear) and the hydraulic characteristics (permeability tests of direct and indirect).
