INVESTIGATION ON TUNNEL RESPONSES DUE TO ADJACENT LOADED PILE BY 3D FINITE ELEMENT ANALYSIS

Finite Element Method Analysis of Influence on Subway Tunnel Adjacent to Excavation by Excavation Construction

The interaction influence on subway tunnels adjacent to foundation excavation was produced by excavation construction, and it is great significance for the correct assessment of its size and influence on the safety of subway operation. Based on the foundation excavation project, some typical foundation excavation profiles are selected, the calculation and analysis on additional settlement and h...

A boundary element/finite difference analysis of subsidence phenomenon due to underground structures

Analysis of the stresses, displacements, and horizontal strains of the ground subsidence due to underground excavation in rocks can be accomplished by means of a hybridized higher order indirect boundary element/finite difference (BE/FD) formulation. A semi-infinite displacement discontinuity field is discretized (numerically) using the cubic displacement discontinuity elements (i.e. each highe...

3D Finite element modeling for Dynamic Behavior Evaluation of Marin Risers Due to VIV and Internal Flow

The complete 3D nonlinear dynamic problem of extensible, flexible risers conveying fluid is considered. For describing the dynamics of the system, the Newtonian derivation procedure is followed. The velocity field inside the pipe formulated using hydrostatic and Bernoulli equations. The hydrodynamic effects of external fluids are taken into consideration through the nonlinear drag forces in var...
