摘要: ABSTRACT A series of K0-consolidation tests in a triaxial cell was carried out for marine clays collected from different areas the world order to investigate behavior during and evaluate K0-values that are required laboratory with recompression techniques, FEM analysis using elasto-plastic constitutive equations, etc. It confirmed famous equation K0NC = 1–sin ϕ′ is useful; however, definition should be concerned. In case ϕ corresponding critical state line, i.e. (q/p)max, underestimates by 0.05; contrast, peak strength, (q)max, overestimates 0.05. This study proposes procedure estimating in-situ K0-value. For representative undisturbed clay sample, K0-overconsolidation (i.e. SHANSEP test) consecutively obtain K – OCR relationship. Using profile obtained oedometer tests, K-value can calculated as K0. The both test fiat dilatometer (DMT field compared well.
