The Research Methods of Mechanical Characteristics on the Soil-Structure Interface

Abstract

There are general three kinds of means to research the mechanical properties of soil-structure interface, and they are soil-structure contact experimental studies, constitutive model and numerical calculation. Through the tests, the observation and measurement results in different experimental conditions can be obtained about soil-structure interface stress-strain characteristics, and then basing on the existing constitutive model theory researchers can put forward reasonable explanation to the phenomenon of the tests. Finally the constitutive model theory can be applied to the numerical calculation to predict and reproduce the test phenomenon, so as to fully reveal the nature of the soil-structure interface mechanical characteristics.
