GEOTECHNICAL AND GEOPHYSICAL.

THE GEOGNOSTIC SURVEYS SERVE TO PROVIDE THE DATA AND INFORMATION NECESSARY FOR GEOTECHNICAL CHARACTERISATION OF THE VARIOUS STRATA OF TERRAIN AND ROCK INVOLVED, ARRIVING AT DEPTHS CORRESPONDING TO THE NEEDS OF THE PROJECTS. BY GEOTECHNICAL CHARACTERISATION WE MEAN THE SET OF INFORMATION AND DATA OBTAINED WITH ON-SITE SURVEYS, DULY INTERPRETED TO PROVIDE AN ADEQUATE DESCRIPTION AND RELIABLE EVALUATION OF THE VALUES OF THE GEOTECHNICAL PARAMETERS, CONSIDERED IN THEIR LIE IN THE SUBSOIL, TO BE APPLIED AT THE PLANNING STAGE. BELOW THEY ARE BRIEFLY LISTED :

  • CONTINUOUS CORE SAMPLING WITH RETRIEVAL OF UNDISTURBED SAMPLES
  • VIBROCORER SAMPLING (CORE SAMPLES OF 3, 6 AND 9 METRES)
  • STANDARD AND DYNAMIC CONE PENETRATION TESTS
  • PRESSUREMETER, FIELD VANE AND DILATOMETER TESTS
  • PLATE LOAD TESTS
  • GEOELECTRICAL PROSPECTING
  • GEOPHYSICAL RADAR PROSPECTING
  • SEISMIC PROSPECTING
  • MAGNETOMETRIC PROSPECTING
  • SOIL AND INTERSTITIAL GAS SAMPLING “GAS SURVEY ”
