Characteristics of Three-Dimensional Flow around Underground Structures
Development of understanding of the mechanics of flow through rock media and its effect on the properties and behavior of rock mass is an important aspect in rock engineering. In this paper, an attempt has been made to present a 3D-finite element formulation for simulating the unconfined flow around underground excavations constructed in isotropic and anisotropic rock media and locate the position of the phreatic surface iteratively. The results thus obtained suggest that a redistribution of pore water pressure is initiated after the excavation of opening and the residual flux with fixed mesh is adequate to locate the phreatic surface. The proposed model has been verified with two examples found in literature.
