OBSERVATIONS ON STRUCTURES

OBSERVATIONS D'OUVRAGES

THE SOIL STUDIES CARRIED OUT BY THE CEBTP DO NOT GENERALLY GIVE THE OPPORTUNITY OF FOLLOWING THE EVOLUTION OF THE STRUCTURE STUDIED, SO THAT THE DEGREE OF ACCURACY OF THE FORMULAE DERIVED IS NOT KNOWN. FURTHERMORE SOME STRUCTURES DO NOT LEND THEMSELVES TO THEORETICAL CALCULATIONS, WHILE IN -SITU MEASUREMENTS WOULD HELP IN MANY CASES TO ESTABLISH A SEMI-EMPIRICAL FORMULA. IT IS PLANNED TO CONDUCT FOLLOW-UP STUDIES OF SOME STRUCTURES, WHICH HAVE ALREADY BEEN INVESTIGATED AT THE CEBTP. IN PARTICULAR, STRESSES IN AN URBAN TUNNEL WILL BE MEASURED AS CONSTRUCTION OF AN IMPORTANT BUILDING COMPLEX PROGRESSES IN THE VICINITY.
