Simulation of sequential excavation with the Boundary Element Method

The paper deals with the application of the Boundary Element Method (BEM) to problems where the boundary geometry and conditions change with time. An example of this is the simulation of sequential excavation in underground construction. A novel approach is presented that is more efficient than the currently used methods. The method involves only one region, where the boundary conditions and the geometry are changed as time progresses. Test examples are presented and results are compared with the ones obtained from other methods. The examples show that the new method is more efficient than currently used methods.
