ABSTRACT
On the basis of the interior terrain of landslide, its relief is descending from north to south. Ganhaizi landslide, about 19790×104 m3, is located on the right bank of the Dadu River. There are two cracks and one creep body in the accumulation of Ganhaizi landslide. The potential slippage volume of the accumulation involved by each deformation body is more than 10 × 104 m3. The middle of the Ganhaizi landslide downstream is a protuberant platform, which makes up of broken and blocky stone with silty soil, and partly includes huge block with original rock sequence that weathering and broken fiercely, its lithology is muscovite-biotitequartz schis. The chief deformed characteristic of Ganhaizi landslide is that there are two deformed cracks and one creep body.
