Leakage analysis and prevention methods of the MENGXI river located in southwest petroleum university

摘要

Based on the mathematical percolation model for fluid in soil medium, the numerical percolation model is established. With the numerical model, the percolation field is analyzed on flow cross section for the artificial river, to understand the performance of river cross section in natural state. With the numerical percolation model and equations for unsaturated state, the infiltration of river water is analyzed, and thus how the sands with different permeability affect the water levels of the river is recognized. In this way, the root causes for dry artificial river are found, so as to provide theoretical basis for percolation prevention for artificial river, and engineering suggestions and measures for long-term water storage.
