多次元圧密問題に対する非線形応カ-ひずみ理論の適用

Abstract

In this report, analysed are multi-dimensional consolidation problems of such clays as pos-sess various elasto-plastic stress-strain relations derived from so-called Dilatancy Theory, mainlyin order to clarify stress paths of some points under embankment.The numerical procedure for consolidation using the finite element method, which origi-nally Christian proposed as a fundamental principle, has been improved for nonlinear problemsand also for stability of calculation.Several results of analysis say that remarkable effects due to dilatancy or plasticity can neverignored in displacement fields and stress paths after beginning of consolidation compared withafter undrained loading process.
