LimitState:GEO是一款协助分析地层数据和解决地层稳定度的工具。   
LimitState:GEO is a groundbreaking geotechnical software product which uses new technology to allow users to more rapidly assess the stability of slopes, retaining walls, footings and virtually any other geotechnical feature. More comprehensive than simple hand-based methods but far easier to use than Finite Element Analysis, with LimitState:GEO you can quickly and easily:    
Analyse geotechnical stability problems of almost any type - including combined problems simultaneously involving slope stability, soil nails, retaining walls, footings and tunnels.     
Find the true failure mechanism and margin of safety without having to pre-determine the type of problem you are facing.     
Identify solutions that are more accurate than can be found using traditional 'automated hand calculation' software.     
Analyse for multiple parameter sets, such as Eurocode 7 Design Combinations 1 and 2, with a single click.     New in LimitState:GEO 2.0   Model soil reinforcement such as rigid and flexible soil nails, as well as sheet pile walls.  Identify failure mechanisms involving rotations, such as overturning of retaining walls, rotation of footings, toppling failure in rock slopes and hinging failures in masonry block structures.  Seismic loading available (since version 2.0c)  Rapidly explore a range of 'what if' scenarios with the ability to undo and redo any edit you make to your model.  More comprehensive report output ( watch video ) and ability to view shear and normal stresses along the edges of solid objects ( watch video ).  More about What's New in LimitState:GEO 2.0 here
