Model ground and structure in one place

LUSAS provides you with a single environment for modelling soil and structure together. Obtain true interaction with detailed modelling of both systems.

Choose the level of soil modelling that suits your needs. Eliminate time wasted and errors introduced exchanging information between different software.

Any geometry, any application

Go beyond the limitation of wizard-based (narrow-scope) software.

Consider foundations, slopes, dams, wick drains, retaining walls and tunnels all in a single model in 2D or 3D.

For rapid draw-down, fracture, ground freezing effects and moving vehicle loads, LUSAS has you covered.

Fast "What ifs"

Soil is unpredictable. Consider best estimate, upper and lower bound properties and assess sensitivity to parametric change.

Your construction methodology might alter. Use branching to assess changes at any stage and the impact on all other stages.

Wide range of soil models

Select the constitutive material models you need to tackle a wide range of geotechnical conditions.

Include softening soils, anisotropic layered deposits, granular materials, clay or rock.

Choose from Hoek-Brown, Modified Cam Clay, Mohr Coulomb, Tresca, Duncan Chang, Drucker Prager and more...

Stability

Perform stability checks, stage by stage drained or undrained.

Apply the same phi-c reduction technique to check on slopes, retaining walls and other soil/structure systems under any set of loads.

Groundwater and flow

Model pore water pressures in drained, undrained, and partial saturation states.

Determine pore water pressures across the model from available borehole data or piezometer readings.

Trace seepage, draw-down, and consolidation through stages of construction.

Construction sequence

Model digging, filling, building, adding/removing props and tunnel parts.

Track time-based effects such as creep and consolidation.

Check results at any stage, including stability or dynamics of part-finished projects.

Dynamics

Earthquakes damage structures and move soil. Use LUSAS to model step-by-step, capturing lift-off and nonlinear effects in materials or shape, as they change over time. Assess the residual strength of the soil and structure and model repairs.

Urban spaces: assess the effect of pile driving on neighbouring infrastructure.

Report, revise, repeat

Present reports tailored to suit your structural or geotechnical checkers. Deliver any format: doc, pdf, xls…

Modify the model and the results and report will change – no problem. Generate an updated report again with a few clicks.

Evaluate different options with multiple and branched analyses and report on them all.

Save the report template or share it, to standardise output across your teams or offices.
