Analysis on Bank Collapse Mechanism of Typical Reaches in Middle and Lower Yangtze River

Abstract

This article analyzes bank collapse characteristics of different river types on the basis of previous research and stable bank slope by combining typical bank collapse samples of the middle and the lower reaches of the Yangtze and other rivers. In combination with the years of statistics of measured data on Daijiazhou section, it also analyzes status, types and features of bank collapse of right edge of Daijiazhou. It analyzes cause and mechanism of bank collapse at right edge of Daijiazhou and predicts bank collapse trend of Daijiazhou by combining the characteristics of bank geology, river regime, local topography of bank slope and hydrology, etc.
