We are using a worldwide well-known finite element software, namely Plaxis, to analyse the retaining wall system and other geotechnical design. It is used to assess the interaction between soil and retaining system and to study the effects of excavation to retaining system (i.e. forces and deflection of wall) as well as to surrounding ground (ground settlement) and adjacent buildings. The software is allowed us to model the actual design system and simulate the construction stages as planned with input of retaining wall type (e.g. concrete pile wall or sheet pile wall), tied-back system (i.e. soil nail, pre-stressed ground anchor and strut), required surcharge, seepage of ground water table, etc.
