A STUDY OF THE DYNAMIC SOIL-STRUCTURE INTERACTION CHARACTERISTICS OF REAL SOIL MEDIA.
Abstract
An experimental and theoretical study of the dynamic soil-structure interaction characteristics of real soil media is presented. An extensive list of the more important references obtained from a literature search is included. Basic concepts of passive and active arching phases of soil-structure interaction, including equations representing static behavior, are presented. The experimental program consisted of a study of the soil-structure interaction on small, idealized, cylindrical structures buried in a sand medium subjected to dynamic loads. Test data obtained indicate that very large overstresses are produced by passive arching. The data also show that overstress due to interaction is dependent upon depth, stress level, relative density of soil, length-to-span ratio, and the compressibility of the structure. The theoretical program consisted of an investigation of the dynamic response of a simple cubic packing of spheres for waves of low stress levels. Certain boundary value problems, representative of phases of soil-structure interaction, were reduced to a form for numerical evaluation. (Author)
