ENGINEERING SITE INVESTIGATIONS IN PERMAFROST AREAS

MOST ENGINEERING PROBLEMS IN PERMAFROST AREAS ARE CAUSED BY THAWING OF PERENNIALLY FROZEN GROUND WHICH CONTAINS LARGE QUANTITIES OF ICE. SUCH ICE SEGREGATION IS MOST SERIOUS IN FINE GRAINED SOILS. THE PAPER DESCRIBES THE SITE INVESTIGATION PROCEDURE TO OBTAIN THE INFORMATION NEEDED FOR DESIGN AND CONSTRUCTION IN THESE CONDITIONS. THE FIRST PHASE CONSISTS OF PRELIMINARY OFFICE STUDIES OF AVAILABLE RECORDS AND AIRPHOTOS AND PLANNING THE FIELD OPERATION WITH ITS PROBLEMS OF ACCESS AND COMMUNICATIONS. THE SECOND PHASE IS FIELD INVESTIGATIONS INCLUDING A GENERAL EXPLORATORY SURVEY FOLLOWED BY DETAILED INVESTIGATION. THE FINAL STAGE PROVIDES FOR CONTINUING OBSERVATIONS AND THE PREPARATION OF REPORTS. THE NEED FOR RECORDING AND EXCHANGING ALL OBSERVATIONS, EXPERIENCES AND CONDITIONS ENCOUNTERED IN THE NORTH IS NEEDED IF GENERAL KNOWLEDGE IS TO BE INCREASED. /CGRA/
