Finite Element Analysis for Excavations and Slopes Phase2 7.0 is a powerful 2D elasto-plastic finite element stress analysis program for underground or surface excavations in rock or soil. It can be used for a wide range of engineering projects and includes support design, finite element slope stability and groundwater seepage analysis. Phase2 7.0 provides material models for rock and soil including Mohr- Coulomb, Generalized Hoek-Brown and Cam-Clay. Complex multi-stage excavations can be easily created and edited using state-of-the-art CAD tools. Groundwater pore pressure can be determined using steady state finite element seepage analysis – flows, pressures and gradients are calculated based on user defined hydraulic boundary conditions. Support Design Phase2 7.0 offers a wide range of support modeling options. Bolt types include end anchored, fully bonded, cable bolts, split sets and grouted tiebacks. Liner elements can be applied in the modeling of shotcrete, concrete, steel set systems, retaining walls, piles, multi-layer composite liners, geotextiles and more. New liner design tools include support capacity plots which allow you to determine the safety factor of reinforced liners. FE Slope Stability One of the major features of Phase2 is finite element slope stability analysis using the shear strength reduction method. This option is fully automated and can be used with either Mohr- Coulomb or Hoek-Brown strength parameters. The analysis parameters can be customized if required. Slope models can be imported from Slide and computed in Phase2 allowing easy comparison of limit equilibrium and finite element results. software tools for rock and soil © 2009 Rocscience Inc. Tunnel
