Tutorial 5: Excavation between two walls connected with a slab Deep Excavation LLC DeepXcav 2011 – Advanced course 1
INTRODUCTION DeepXcav is a software program for braced excavations in soils with 2D limit-equilibrium and non-linear analysis methods, and structural verification of all elements (with AISC, ASD, Eurocodes). It offers the ability to analyze walls with multiple braces (tiebacks) in multilayered soils. The non-linear analysis considers elastoplastic behavior for the whole soil-wall-support system. The program also offers the ability to perform traditional limit-equilibrium analyses. The graphical interface is completely interactive and the input is simplified to a great extend. The program utilizes archives of wall types, structural and soil materials, ground anchors etc. The analysis can be performed in either an utlimate state or at a service state (allowable design or LRFD). The program offers the ability to automatically set all critical settings according to the desired design methodology. The program also offers the ability to perform slope stability analyses with soil nails. Corso Paratie, Milano 30 settembre 2009 DeepXcav 2011 – Advanced course 2
