Study on Finte Element Modeling of ComPressed Structure Stress Field in beijing West Suburb coal Basin

The paper deduced the azimuth of three-dimentional stress axes of different-scale folded structures in an invetigated area of Beijing west suburb coal basin, and reconstructed stress field of compressed-structures in the Early Yanshan Movement.The finite element modeling was made for two-dimentional plane stress field on the basis of the above-study.
