Calculation of earth-rock dam seepage based on boundary element method with the infinitely deep permeable foundation Liang-Liang Chen, Liang Ma, Feng Liu School of Water Resources and Civil Engineering, Xinjiang Agricultural University, Urumqi 830052, China Keywords: infinite deep permeable soil;earth-rock dam; seepage; boundary element method Abstract.
Introduction Seepage analysis is an important part of the design of hydraulic structures, security and economy of its embankment dams and other engineering structures has important implications.
Using the boundary element method to establish the blanket impervious embankment dams built in the infinitely deep permeable foundation seepage calculation model, the preparation of the corresponding computer program, and verify the validity of the model, provide a reference for engineering design.
And with an engineering example for seepage calculation, verify the feasibility of the model.
