Study on Soil Structural Parameters under Confined Compression Condition Based on Gunary Model
The study of soil structural parameters is an important and difficult research content in geotechnical engineering.Some stress-controlled and strain-controlled confined compression tests are carried out to investigate soil structural parameters.The new stress-strain relation representing formula
the Gunary model
and the secant modulus method are used.A simplified and applicable single variable soil structural parameter model under confined condition has been given.Based on the comparison between laboratory tested values and calculated values
the authors prove the strain-considered structural parameter calculated values with stress
and the stress-considered structural parameter calculated values with strain separately conform to the quadratic polynomial and the two-parameter linear reciprocal function form
and demonstrate the rationality of the Gunary model to study soil structural parameters.
