For seepage analysis using Composite Element Method(CEM), the drainage holes are treated as “air sub-elements” with high permeability contained in the conventional rock(soil) element, which is called “composite element”. To ensure the validity and correctness of the calculated results, the “permeability coefficient” of drainage holes and transmissibility coefficient of the interface between rock(soil) and drainage holes are studied and some reasonable suggestions are given. To improve the calculation precision and efficiency of CEM, the p-version adaptive method is studied and the corresponding algorithm of upgrade the hierarchical order and accelerating convergence are implemented in the CEM.
