Experimental Investigation on the Breach Process and Stability Evaluation of Cohesive Levee

Key Points

• The main aim is to investigate the breach process and evaluate the stability of cohesive levees.
• Conducted full-scale levee breach experiments to observe behavior during failure.
• Detailed analysis of breach mechanisms based on soil mechanics principles.
• Introduced a canti-lever failure model for assessing the stability of overhanging levee sections.
• Identified that cohesive levees tend to slip or rotate during failure.
• Found that the erosion of the foundation influences the loss of the levee crest and face.
• Demonstrated compatibility of the canti-lever model with experimental results, suggesting its potential application.
