Abstract
The landslides and rockfalls were studied in this paper from Xiangjiaba to Baihetan in the lower reach of Jinsha river. Their volume, distribution density and landslide index were studied which indicated that there existed close relationships between landslides and rockfalls and geological structure, stratum. The fold and faultage influenced on the stability of slope and offered the geological condition to landslides and rockfalls. The physiognomy controlled their distribution. Slope angles of landslides were 10°–50° and slope angles of rockfalls were mainly 35°–50° in the valley in the studied area. The results indicated the geology and physiognomy of distribution area of the landslides and rockfalls in the studied area. They offered the theoretical foundation to prevent and cure geological disaster and protect the water power engineering.
