STUDY ON GEOLOGICALLY DANGEROUS SECTIONS OF ENBANKMENT OF LOWER YELLOW RIVER

The geologically dangerous sections formed by geologic agent can be distinguished into three kinds, such as neotectonically dangerous section, subsidence - dangerous section, and reactivation-dangerous section. Percolation sections of embankment foundation, earthquake damage sections, and weak stability sections of embankment foundation are of a part of geologically dangerous sections. According to the geological features of the lower Yellow River, three Geologically dangerous sections can be identified, such as Dongbatou, Daliutun-Dongkou, and Lunali-Shilipu sections. Some countermeasures are suggested in this paper.
