Abstract: The Baiyian 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.
