Abstract: | Along with the vigorous developing construction, the
number of various underground engineerings is greatly increasing, such as the foundations of
dams and high_rised multistored hauses, the subways and the tunnels, the water and oil wells
etc., where the close attention is always paid to the seepage behaviour in the media around the
structures. The variational inequality formulation and its FEM solution for the free boundary
problem of 2D steady state seepage flow was given by She Yinghe et al. In this paper, a further
investigation is made on the non_steady state seepage problem, by taking the seepage flow of
wells as an example. The presented approach variational inequality and its FEM solution is
also very beneficial to the non_steady state problems, where the transient free boundary can
also be defined directly without conventional iterations. |
