PARTICLE DISPLACEMENT DURING SHEAR DEFORMATION OF SOILS

KORNUMLAGERUNG BEI SCHERDEFORMATIONEN VON BOEDEN

THE QUESTION OF PARTICLE DISPLACEMENT PLAYS A VERY IMPORTANT PART IN NEARLY ALL SOIL MECHANICS PROBLEMS, SUCH AS FOR EXAMPLE THE STABILITY OF SLOPES, THE SETTLEMENT OF THE SUBSOIL, THE HYDRAULIC FAILURE OF STRUCTURES AND THE CASE OF PRESSURE DISTRIBUTION UNDER SLABS AND NEAR RETAINING WALLS. CLARIFICATION OF THE PROCESSES WHICH OCCUR DURING THE DISPLACEMENT OF SOILS IS THEREFORE A BASIC PROBLEM. ITS SOLUTION WILL OF COURSE NOT LEAD TO IMMEDIATE ECONOMIC SUCCESS, BUT CONTRIBUTE TO THE UNDERSTANDING OF ALL SOIL MECHANICS PROCESSES AND THEREFORE IN THE FINAL ANALYSIS WILL EFFECT MORE ECONOMIC DESIGN. THE AIM OF THE RESEARCH PROJECT IS TO EXAMINE PARTICLE DISPLACEMENT IN SANDS AND SIMILAR SOILS UNDER THE INFLUENCE OF SHEARING OR SETTLEMENT. THIS IS AN AREA IN WHICH UP TO NOW ONLY A FEW STUDIES HAVE BEEN MADE AND THE PROSPECT EXISTS THAT THE CLARIFICATION OF THIS QUESTION WILL PROVIDE BASIC KNOWLEDGE ON THE BEHAVIOUR OF SOILS.
