Genesis and stability of the Zhoujiawan landslide, Three Gorges, China

The development of the Three Gorges project has resulted in the study of a number of landslides along the Yangtze River. This paper discusses three landslides in the Huanglashi group, some 66 km upstream of the Three Gorges dam. It describes the development and inter-relationship of these landslips, which occurred on the concave meander of the river where steep slopes were created by uniclinal shifting as incision took place. Finite element analysis was used to assess the most likely zone in which future failures will occur.
