摘 要：基本完成了SAP84-NOLM的PC版本并進行了測試，可以實現在PC上計算大約30萬自由度的地質體結構。其中包括帶有裂隙的地質體的初始網格生成和裂隙擴展時的網格自適應；2D/3D滲流場的計算；用弧長法來計算材料的軟化，以考慮水對地質體本構的影響以及大規模并行計算的初步實現。小尺寸滑坡物理測試平臺已經完成并進行了實驗，大尺寸滑坡物理測試平臺正在施工建設中。

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
