Experimental Investigation for Dynamic Response of Saturated Clay Under Machine Foundation

Abstract

A machine foundation is considered important and because of that the foundation design under dynamic loads must be governed by serviceability limit states performance considerations rather than strength requirements. The dynamic response is carefully calculated to ensure high-quality and efficient performing for machinery. This paper presents a model for estimating the dynamical response of a machine foundation on saturated clay by experimental work. The machine is produced to simulate forced vibrations by harmonic loading at various operating frequencies. The depth influence of embedding and load frequency on model footings on soft clay soil is investigated. As well as, stresses and excess pore water pressure get measured at different depths in the soil below the footing. It was concluded that the maximum displacement increases as the operating frequency increases, as well as, there is an increase in the excess pore water pressure when the dynamic load increases.KeywordsDynamic analysisDynamic responseSaturated clayMachine foundationPore water pressure
