摘要
在青藏高原东部边缘地带的共和盆地中,滑坡堆积体的剖面形态,大多具有多级台阶的特点,组成物质单一,整体性较好,岩层的后半部分普遍出现明显的反翘现象,且滑体结构不够紧密。考察中发现,滑动面具有前缘滑移面、后缘拉裂面和中间剪断面的三段式形态。滑坡构造包括褶曲及柔皱构造、砂脉、砾石脉和泥膜等。
In the Gonghe basin on the eastern periphery rank of Ti- bet plateau the section form of piled body from landslide have mostly multiple terrace,the character of single composition materials and better entirety,the latter part of the rock layer shows obvious reverse bend, the sliding body is not seperable.It is found in the survey that the sliding surface has a three segments form,including sliding surface of forward edge,drawing open surface of back edge and shearing surface of inter part.The tectonics of landslide include wrinkle and folding tectonic,sand vein,stone vein and mud film,etc.
