Abstract

Reservoir bank collapse, which strongly influences the relocation area when water is impounded, is currently an important topic in reservoir engineering. In this work, a series of orthogonal experiments was carried out to analyze, from among the many factors that can affect bank collapse width (BCW), the effects on BCW of slope angle, material grain-size diameter, degree of density of material, wave height of reservoir water, and water level fluctuation. A detailed analysis of each parameter is presented, and the analysis of range (ANORA) calculated. The results of the study show that the most sensitive factor affecting BCW is slope angle, followed by density degree, clay proportion, wave height, and water level. Finally, a prediction formula was established based on the physical simulation experiments, and its scope of applicability is discussed. These research results provide a reliable basis for future bank collapse studies.
