摘要
由地质作用影响形成的易出险堤段称为地质险段 ,主要包括活断层作用影响形成的堤基易渗漏段、强地震高发区段和地基稳定性差段等。构造节点是识别地质险段的重要的河流地貌标志之一。根据成因 ,本文将黄河下游的地质险段分为三类 ,即新构造险段、沉降险段、断裂复活险段。针对黄河下游堤防地质特征 ,圈定出东坝头、大刘屯—董口黄河南岸和路那里—十里堡黄河南岸地质险段 。
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.
