Abstract：The PC version of SAP84-NOLM package is completed basically and tested. The capacity of the package is that the geological body with 300000 DOFs can be simulated.The package includes the following function modules：initial mesh generation for cracked geological body and the adaptive technique for crack extension；2D/3D computations for seepage；computations of material softening by arc-length method to take into account the effects of raining on constitutive relations of geological body and the preliminary realization of large size parallel computing.A small size of physical testing platform for slope has been constructed and several in-house testing was completed.A large size of physical testing platform for slope is in construction.

Key Words：Landslide；Stability；Mesh generation；Testing platform；Seepage
