| 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。

| Abstract: | 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. |

| Keywords: | Helanshan NNE-trending structure reversed s-shaped structure |
