Paper Title:
Rational Calculation Model of Interlayer Separation of Complex Roof in Deep Coal Tunnel
  Abstract

In order to reasonably analyze interlayer separation of complex roof in deep coal tunnel, the rational calculation model was chosen and distribution of normal stress, shear stress and interlayer separation of construction surface in elastic and plastic conditions were analyzed in different original rock stress. In order to analyze varying interlayer separation with time, rational creep model was chosen and the results were drawn that plastic deformation of complex roof had obvious influence on interlayer separation and numerical simulation agreed well with the actual varying interlayer separation with time by burger creep viscoplasticity model to analyze creep characters of complex roof.
