| 摘 要： | 咸阳地裂缝出现于1992年,以近东西向为主,局部发育为近南北向,水平拉张位移最明显,垂直位移次之,水平扭动位移最小,为拉张兼具左旋地裂缝。咸阳地裂缝的出现位置与区域构造线吻合,说明与区域地质构造环境密切相关,构造带的存在与活动为地裂缝的发育提供了空间条件和力学薄弱界面,而承压水头的急剧下降,最终使地裂缝的出现成为可能。

| Abstract: | The ground cracks appeared in Xianyang in 1992,mainly in the near north-south direction and partly in the near east-west direction.Stretched displacements are the most,then the vertical displacements and the horizontal twisted displacements in the least.So they are stretched cracks revolving to the left.Their locations are consistent with regional tectonic lines,which explains that they are closely related to the regional tectonic zone.The occurrence and movement of the tectonic zone provide the spatial conditions and interfaces with weak mechanics for the development of ground cracks while the rapid decrease of water level makes the ground cracks come into being. |
