Applications of manifold method to geotechnical problems involving ezcavations

摘要：

Manifold method (MM) is a powerful numerical analysis method to simulate displacements and deformations of the ground including discontinuous planes such as joints and faults. However, MM lacks some practical functions in order to simulate geotechnical problems. We have equipped the MM with excavation process and material boundaries. The excavation is realized by releasing the contacts between surrounding area and excavation area which area bounded by joints. The material boundaries are formulated as a boundary between the elements, which share common cover mesh (mathematical mesh). Some example results indicate the MM will be applied to a simulation of geotechnical problems involving excavations.
