Abstract

With the application of continuum theory of mixture

a fully coupled mathematical model and the governing differential equation of the coupled problem of temperature

seepage and stress fields for equivalent continuum media of fissured rock mass are established.A set of fully coupled finite element formulae are obtained by fully coupled methods

and a 2-D finite element program for solving the equation is developed.The calculation results given with calculation example well reveal the varied behaviour of displacement

pore pressure and temperature under coupled action of seepage

stress and temperature

which indicates the mathematical calculation model and numerical program developed are reasonable and practical.
