    • Taking the bank collapse in front of the Cizhong resettlement site of the Wunonglong Hydropower Station on the Lancang River as an example, this study analyzed the bank collapse mode and,causative mechanisms, predicted the width and elevation of the bank collapse, and proposed remediation strategies and protective measures. Through on-site drilling exploration, surveys of influencing factors, analysis of causative mechanism, and the development of prediction methods, the study employed the Kachugin method, bank slope structure method, and finite element method for prediction. The bank collapse in front of the Cizhong resettlement site features high, steep soil slopes, prone to a collapse-and-retreat type of failure. The main influencing factors are the softening of the rock-soil mass post-impoundment, bank slope geometry, stratigraphic structure, topflow erosion, and housing loads. Predictions by the Kachugin method suggest a relatively large range of bank collapses. The predictions by the bank slope structural method and the finite element method are closely aligned in terms of predicted range. The location of the bank collapse is situated towards the middle to the rear of the No. 1 subsidized rental housing. The predicted bank collapse width is about 52 meters, and the elevation is about 1945 meters. The bank collapse greatly impact poses significant risks to the surrounding environment, affecting the stability of the adjacent bank slope and local traffic, potentially impacting the subsidized housing adversely if not timely addressed, with risks of adverse effects and overall structural failure. The research results are of significant importance for the prevention and control of the bank collapse at the front edge of Cizhong and can provide references for other similar regions, offering practical application value in engineering applications.
