白衣庵滑坡的新认识

SOME NEW FINDINGS ON THE BOUNDARIES OF BAIYI'AN LANDSLIDE IN FENGJI,THREE GORGES

白衣庵滑坡是奉节地区争议最大的一个滑坡,本文通过大量细致的地面工作,从外围逐点逼近的工作方法,再结合一些探槽并辅以大面积的可控源音频大地电磁法(简称CSAMT)对白衣庵滑坡进行调查。作者得出以下新认识:(1)鸡骨梁前缘剖面出露岩体结构完整,不应是滑坡体;(2)李家沟两侧岩体连续,不能作为滑坡边界;(3)白衣庵滑坡东侧边界大致以卢家沟为界,西侧在水井槽东侧部位,上部东侧边界靠近柑子林,其后部可达老苍屋平台一带。

The Baiyi＇an landslide in Fengji region, Three Gorges is a landslide without a consensus understanding among the researchers. The paper includes detailed geological mapping on the slope surface. The exploratory trench and CSAMT are also used The field data show some new findings of the landslide. At first, the integrity outcrop at the front of Jiguliang is not the landslide substance. Next, because the rock mass is connected at the two sides of Lijiagou, o Lijiagou is not the boundary of landslide. Moreover, Lujiagou is the eastern boundary of Baiyi＇an landslide, and the eastern Shuijingcao is the western boundary of Baiyi＇an landslide, and the Ganzilin is the upside boundary at the eastern side, and the Laocangwu platform is the rearward region of the landslide.
