窝崩是长江中下游地区最大规模的地质灾害,在很短的时间内就可造成大量的土体塌失,严重威胁生命财产。为针对性防护窝崩,以南京三江口地区窝崩为例,分析了窝崩成因与发生过程,并探讨了河岸的两种破坏类型。结果表明,水流冲刷是发生窝崩最重要的因素。 Nest collapse is the largest geological disaster in the middle and lower reaches of the Yangtze River. In a very short period of time, a large number of soil collapses and a serious threat to life and property can be caused. In order to protect the nest from collapsing, a case study of nest collapse in Nanjing Sanjiangkou area was taken as an example to analyze the causes and occurrence of nest collapse and to discuss two types of damage. The results show that water scouring is the most important factor for nest collapse.
