DETERMINATION OF THE VOLUME CHANGE MODULI AND RESPECTIVE INTER-RELATIONSHIPS FOR TWO UNSATURATED SOILS

A high percentage of earth engineering problems involve unsaturated soils. The ability to describe and predict the volume change behaviour of unsaturated soils is important for geo-environmental and geotechnical analyses. Volume change for an unsaturated soil is described by two independent constitutive relations defined by stress state variables and material properties called volume change moduli. Understanding the volume change behaviour requires a knowledge of the volume change moduli on four state planes. This paper presents the findings of a test program which has measured the volume change moduli for two unsaturated soils, on "identical" specimens. The results are used to illustrate the inter-relationships between moduli. (A) For the covering abstract see IRRD 881647.
