THE CURRENT STATUS OF SOIL DYNAMICS

THE FOLLOWING THREE MAIN BRANCHES OF SOIL DYNAMICS ARE DISCUSSED: MACHINE FOUNDATIONS, PROTECTIVE CONSTRUCTION AND EARTHQUAKE ENGINEERING. WHILE MANY PRINCIPLES AND METHODS OF ANALYSIS ARE COMMON TO THE THREE BRANCHES, THERE ARE IMPORTANT DIFFERENCES BETWEEN THEM, NOTABLY IN THE MAGNITUDE OF STRESSES AND RESULTANT STRAINS. A LITERATURE REVIEW IN SOIL DYNAMICS SHOWS THAT PROGRESS HAS COME AND WILL CONTINUE TO COME THROUGH A SKILLFUL BLENDING OF THEORETICAL ANALYSIS, EXPERIMENTAL STUDY OF SOIL BEHAVIOR, EXPERIMENTS UPON MODELS OF SOIL-STRUCTURE SYSTEMS, AND OBSERVATIONS OF THE PERFORMANCE OF COMPLETED SOIL-STRUCTURE SYSTEMS UNDER SERVICE CONDITIONS. ALTHOUGH ELEGANT METHODS OF THEORETICAL ANALYSIS ARE NECESSARY AND APPROPRIATE FOR RESEARCH, PRACTICAL DESIGN MUST BE ADDED BY SIMPLE EQUATIONS WHOSE COEFFICIENTS CAN BE CHOSEN TO BE CONSISTENT WITH PAST EXPERIENCE. IT IS CONCLUDED THAT THERE IS A GREAT NEED FOR OBSERVATIONS OF THE PERFORMANCE OF COMPLETED SOIL-STRUCTURE SYSTEMS SUBJECTED TO DYNAMIC LOADINGS.
