摘要: 渭河盆地是我国现代构造活动十分强烈的地区之一,活断层纵横交错、相互切割,发育地裂缝近212条. 为了研究渭河盆地地裂缝的同生机制,通过地面调查、测绘、探槽、钻探和物探等地质勘探手段,分析渭河盆地地裂缝发育的同生条件和同生特征,总结提出该盆地地裂缝的同生机制. 主要结果有:(1)渭河盆地地裂缝具有较为明显的同生条件,它们处于同一盆地构造框架内,受同一构造应力系统驱动,从而形成了相似的地表破裂系统;(2)渭河盆地地裂缝的同生特征有平面展布的方向性、剖面结构的相似性、与断裂的普遍关联性和活动时间的同步性;(3)渭河盆地地裂缝形成的同生机制包含了四个层次的内容,分别是上地幔隆升的宆拱机制、中上地壳流展的拉伸机制、断块差异运动的牵动机制和断裂伸展蠕滑的破裂机制. 渭河盆地地裂缝破裂系统受控于上述的四个构造动力机制,它们之间相互联系,相互依托,密不可分. 研究渭河盆地地裂缝的同生机制,对于地裂缝生成机理的宏观认识具有着重要的价值,对于地裂缝区域性的防灾减灾具有重大的现实意义.
