摘要: 本文采用服从抛物线型破坏准则的滑移线场理论,对重力构造的铲式断层进行了力学研究。岩层重力滑动的坡度与岩石强度、滑动系统厚度、孔隙压力以及润滑层有关;铲式正断层自上至下由张性、张剪性、纯剪性过渡到压剪性,铲式逆断层上下一致为压剪性。

Abstract: In this paper,mechanical researches are done for the listric faults of gravitational structure by means of the slip-line field theory obeying parabolic failure criterion.Slopes of gravitational gliding are related to rock strength,thickness of sliding system,pore fluid pressure and lubricating layer;from top to bottom,the listric normal faults change from tensile to tenso-shear,pure shear and compresso-shear and the reverse listric faults are entirely compresso-shear.
