MEASUREMENT OF THE COMPLEX MODULI AND DAMPING OF SOILS UNDER DYNAMIC LOADS. LABORATORY TEST APPARATUS PROCEDURE AND ANALYSIS.

Abstract

A laboratory method is described which is currently being used to investigate the required soil properties necessary in solving foundation design problems for facilities that incorporate dynamic or vibration loading within the structure and have extremely high stability requirements. Emphasis is placed on the test apparatus, nomenclature, and the analysis and computation of the test results. It has been determined that the moduli and damping vary with soil physical conditions (density, water content, degree of saturation, etc.), static load conditions (vertical and lateral pressures), and dynamic loading conditions (frequency, drive force, and drive amplitude).
