Abstract

For a wide variety of geomaterials, cohesionless and cohesive soils and sedimentary soft rocks and cement-mixed soils, the importance and advantages of measuring the deformation characteristics accurately and continuously for a strain range from less than 0.001 % to several % by a single static test using a single specimen are demonstrated. It is also shown that the deformation characteristics at strains of less than about 0.001 % is essentially elastic and the elastic stiffness values evaluated under static (monotonic and cyclic) and dynamic (fast cyclic) loading conditions are the same from the engineering point of view. It is discussed that the plastic deformation characteristics including the damping ratio, the decay characteristics of stiffness and the liquefaction potential are not uniquely linked to the elastic properties.

Deformation Characteristics of Soils and Soft Rocks under Monotonic and Cyclic Loads and Their Relationships

St. Louis, Missouri

For a wide variety of geomaterials, cohesionless and cohesive soils and sedimentary soft rocks and cement-mixed soils, the importance and advantages of measuring the deformation characteristics accurately and continuously for a strain range from less than 0.001 % to several % by a single static test using a single specimen are demonstrated. It is also shown that the deformation characteristics at strains of less than about 0.001 % is essentially elastic and the elastic stiffness values evaluated under static (monotonic and cyclic) and dynamic (fast cyclic) loading conditions are the same from the engineering point of view. It is discussed that the plastic deformation characteristics including the damping ratio, the decay characteristics of stiffness and the liquefaction potential are not uniquely linked to the elastic properties.
