摘要
贺兰山ＮＮＥ向反“Ｓ”型构造由一系列褶皱、断裂组成，相互平行，略显斜列。构造形迹多表现为压扭性，且以压性为主，兼有反扭。对其构造特征、力学成因和成生发展史，前人仅有定性描述。本文从弹性力学角度半定量－定量来求解该问题，并给出一个数学力学模型，较圆满地解释了贺兰山ＮＮＥ向反“Ｓ”型构造的力学成因。
The reversed “S” shaped structure consists of series of NNE trending folds and faults,which are mutually parallel and en echelon arranged.The component structures are mostly expressed as compress shear elements,with sinistral motion predominated.They were only qualitatively described previously.This article,however,gives a mathematical mechanical model for its formation.
