Efficient Computation for a Complex Tunnel Excavation Problem
Computational efficiency is of critical importance in the application of large-scale finite element simulations for solving complex geotechnical problems. This paper summarizes the formulation and implementation of a FETI domain decomposition technique for parallel finite element computations, highlighting the parallel efficiency and scalability of the software using a cluster of 16 interconnected commodity computers. The program is then used to simulate ground movements caused by the construction of a shallow cavern for a new subway station using a stacked-drift tunneling method which involved hand-excavation of a sequence of 15, 3m-square-section drifts through weathered alluvial soils.
