RAILWAY EMBANKMENTS WITH SETTLEMENT

THE COMPLEX CHARACTERISTICS OF ELASTIC COMPRESSION CONSIST OF AN INITIAL COMPACTION CURVE AND A NUMBER OF ELASTIC COMPRESSION CURVES CORRESPONDING TO VARIOUS POINTS, 1, 2, AND 3, ON THE INITIAL COMPACTION CURVE. THE INITIAL COMPACTION CURVE ESTABLISHES THE RELATIONSHIP BETWEEN THE PRESSURES DEVELOPING IN THE SOIL AND THE POROSITY FACTORS AT WHICH ONLY REVERSIBLE DEFORMATIONS APPEAR IN THE SOIL A REVERSIBLE /ELASTIC/ COMPRESSION CURVE MEANS A CURVE IN WHICH THE LOADING AND THE UNLOADING PORTIONS PRACTICALLY COINCIDE. THE TESTING OF SOILS FOR PLOTTING THESE COMPLEX CHARACTERISTICS SHOULD REFLECT, AS CLOSELY AS POSSIBLE, THE CONDITIONS AND THE NATURE OF OPERATION OF THE OBJECT UNDER CONSIDERATION, INCLUDING THE NUMBER OF TIMES THE ROLLING STOCK ACTS ON THE SOIL AND THE DYNAMICS OF THIS ACTION. FOR AN APPROXIMATE SOLUTION ORDINARY COMPRESSION CURVES MAY BE USED WITH THE INTRODUCTION INTO THE CALCULATIONS OF A FACTOR K TAKING INTO ACCOUNT THE THE PERIODICITY, DURATION, AND METHOD OF APPLICATION OF THE LOAD. ONE EQUATION CAN BE USED FOR CALCULATING THE VERTICAL STRESSES IN EMBANKMENTS CAUSED BY A MOBILE LOAD. ANOTHER EQUATION IS EMPLOYED TO DETERMINE THE CONSTRUCTION RISE OF THE ROAD BED. /AUTHOR/
