Analysis of bank collapse characteristics and causes of typical nest collapses in the Jiangsu section of the Yangtze River
摘要
Abstract
Bank collapse is a severe natural disaster that frequently occurs along the banks of the middle and lower reaches of the Yangtze River.It is characterized by complex characteristics of high frequency,concealment,and destructiveness,posing a serious threat to people's lives and property.The Jiangsu section of the Yangtze River is also a frequent occurrence area of bank collapse.Based on the statistical analysis of historical measured data of bank collapse in the Jiangsu section of the Yangtze River,this paper clarifies the characteristics that the Jiangsu section of the Yangtze River is dominated by nest collapse.On this basis,through the analysis of the measured hydrological,sediment and topographic data before and after the occurrence of typical nest collapses in Youzhuangwei of Sanjiangkou in the Nanjing reach,the left branch of Hechangzhou in the Zhenjiang-Yangzhou reach and Zhinan Village in the Yangzhong reach,the main controlling factors for the occurrence and development of large scale nest collapses are clarified.Based on the analysis of the characteristics of bank collapse in the Jiangsu section and the main controlling factors for the occurrence and development of typical nest collapses,it is shown that hydrodynamic forces,riverbed evolution,bank slope characteristics,and human activities are the four major categories of factors affecting bank collapse in the Jiangsu section of the Yangtze River.However,the weights of various factors along the Jiangsu section vary to a certain extent.关键词
