以龙门山断裂带北段中的青川断裂、茶坝-林庵寺断裂沿线的地质地貌为研究对象,在青川断裂沿线的土关铺、大安,茶坝-林庵寺断裂上的薛家沟、胡家坝等地,对断裂附近的河流地貌进行了详细的构造地貌制图。
3.
The Longmenshan fault zone is a huge multiple thrust fault at the middle on the eastern margin of the Qinghai-Tibet Plateau.
本文通过对龙门山断裂带中段后山断裂带主要断裂的研究,认识到从茂汶断裂往西北到挂思岭断裂,断裂最新活动时代有逐渐变老的趋势,反映了龙门山后山断裂在晚新生代同样具有前展式(背驮式)逆冲推覆特征,主断裂茂汶断裂的最新活动时代为晚更新世晚期;后山断裂带除逆冲挤压构造变形外,还存在拉张变形,这为研究青藏高原的运动学及动力学等问题提供了重要信息。

The results show that before the earthquake the regional deformation were staged,in detail,its differential elevation and subsidence weakened and the movement of Longmenshan fault turned from active to locked,after the earthquake,the earthquake effect spreaded north-east ward along the Longmenshan fault mainly and the co-seismic deformation nearby the after s.
结果表明:震前,区域垂直形变表现出某种阶段性,升降差异运动由剧烈向减弱变化,龙门山断裂活动也由活跃向闭锁转换;震后,地震影响主要沿龙门山断裂带向北东方向扩展,余震区附近同震形变显著。

补充资料：断裂带
亦称“断层带”。有主断层面及其两侧破碎岩块以及若干次级断层或破裂面组成的地带。在靠近主断层面附近发育有构造岩，以主断层面附近为轴线向两侧扩散，一般依次出现断层泥或糜棱岩、断层角砾岩、碎裂岩等，再向外即过渡为断层带以外的完整岩石。断层带的宽度以及带内岩石的破碎程度，决定于断层的规模、活动历史、活动方式和力学性质，从几米至几百米甚至上千米不等。一般压性活压扭性断层带比单纯剪切性质的断层带宽。在一些大型的断层带中，由于被后期不同方向的断层切错，和夹有一些未破碎的大型岩块，只是断层带的结构趋于复杂化，从而在近代的断层活动中容易形成运动的阻抗，是应力易于积累和发生地震的场所。
