【 摘 要 】

Seepage control is one of the key technical problems faced by mountain river embankment construction. Seepage analysis is an important way to achieve optimal design of dike seepage control. The floods of mountainous rivers are steeply rising and falling, the peaks are concentrated and short. The dikes are relatively difficult to form stable seepage. Taking the river dike in the upper reaches of Xinxi River in Jinyun County as an example, this paper comprehensively analyzes the characteristics of topography, geological structure and anti-seepage scheme, establishes the three-dimensional finite element model of the dike, and uses the parabolic Signorini-type variational inequality method to calculate the unstable seepage of the embankment. The research results have a guiding significance for the optimal design of seepage control measures for mountain river embankments.
