THE CREEP STABILITY OF SOILS (PRELIMINARY STUDY)

KRIECHSTABILITAET VON BOEDEN (VORSTUDIE)

AS REGARDS EFFORTS TO ACHIEVE AS ECONOMICAL A DESIGN AS POSSIBLE IN EARTHWORKS AND FOUNDATION ENGINEERING,AND SIMULTANEOUSLY TO ACHIEVE INCREASING USE OF SOILS RICH IN CLAY WHICH DO NOT HAVE SUCH A HIGH BEARING CAPACITY,THE APPEARANCES OF CREEP OBSERVED IN THE LABORATORY AND IN SITU INCREASINGLY FORM A PROBLEM WHICH IS UNSOLVED.UNDER CONTINUOUS LOADING NEARLY ALL SOLID MATERIALS SHOW LOW-RATE, LONG-LASTING DEFORMATIONS WHICH ARE CALLED CREEP.IN THE MULTI-PHASE MATERIAL SOIL,THE RHEOLOGICAL AND ENGINEERING RELATIONS OF THIS PHENOMENON EXTEND FROM UNEXPLAINED PHYSICAL/CHEMICAL PROCESSES TO QUESTIONS OF THE EFFECTS ON ARTIFICIAL AND NATURAL SLOPES.FROM THE SOIL MECHANICS ANGLE IT IS A QUESTION OF CONSIDERING THE INFLUENCE OF TIME WHEN RELATIONS BETWEEN STRESS AND DEFORMATION ARE DETERMINED (INCLUDING TIME STABILITY).THE ANALYSIS OF THE PROBLEM (PART 1 OF THE PROJECT) EXTENDS TO THE SYSTEMATIC DETERMINATION OF THE NUMEROUS INDIVIDUAL PROBLEMS OF CREEP IN SOILS,WHEREBY ALL QUESTIONS RELATING TO SOIL MECHANICS, EARTHWORKS AND FOUNDATIONS ARE TO BE CONSIDERED.THE DRAWING UP OF RESEARCH PROGRAMMES (PART 2 OF THE PROJECT) DEPENDS ON THE EVALUATION OF THE PROBLEM ANALYSIS; A LIST OF INDIVIDUAL RESEARCH PROGRAMMES ARRANGED IN ORDER OF PRIORITY IS TO BE SUPPLIED.
