OBSERVATIONS ON THE BEHAVIOUR OF SOILS AND ROCKS ROUND UNDERGROUND STRUCTURES

CONSTATATIONS SURLE COMPORTEMENT DES TERRAINS AUTOUR DES OUVRAGES SOUTERRAINS

THE AIM OF THIS STUDY, CONDUCTED IN COOPERATION WITH THE C.E.T.U., IS TO COLLECT AND ANALYZE OBSERVATIONS ON GALLERY SITES WITH A VIEW TO DETERMINING THE MAIN GEOLOGICAL AND GEOTECHNICAL PARAMETERS AS REGARDS CONSTRUCTIONAL DIFFICULTIES. OBSERVATIONS MADE ON VARIOUS SITES WILL BE SUMMARIZED. EMPHASIS WILL BE PLACED ON THE QUANTITATIVE ASPECT OF THE OBSERVATIONS: CORRELATIONS BETWEEN QUALITATIVE DATA AND MAIN GEOTECHNICAL CHARACTERISTICS, DEVELOPMENT OF SIMPLE MEASURING TECHNIQUES, IN-SITU MEASUREMENTS AS THE WORK PROGRESSES ON THE CONSTRUCTION SITE (IN PARTICULAR DEFORMATION MEASUREMENTS).
