Abstract: Examination of the available literature at home and abroad and authors in situ investigations led to find that landslide dams and dammed lakes lie mainly in mountain zones. The study indicates that the engineering geological problems of landslide damming mainly include infiltrational deformation, stability, settlement, and liquefaction of sand layers. The above engineering geologic problems are discussed in this paper for landslide damming, and its utilization is analysed on the basis of an actual examples. So, this paper provides a guide for exploration of landslide dams and dammed lakes.
