Innovative cloud based apps for geotechnical engineers 

 

APPS

LAP

LAP is an application for analyzing the response of piled foundations subjected to lateral loads and is a stunningly simple alternative to existing desktop applications. LAP includes both non-linear p-y models and an ability to incorporate non-linear M-theta rotational springs that particularly important for large diameter mono-pile foundations for offshore wind turbines. LAP is used by large energy companies, many top tier engineering consultancies and universities throughout the world.

IMPACT

IMPACT is a cloud based application for analysing the driving performance of pile foundations using a 1-dimensional wave equation model. The interaction between pile and soil is captured by non-linear springs and dashpots distributed along the pile shaft and base. The pile-soil springs are based on theoretical continuum models and because the internal soil column is treated explicitly, with separate interaction springs compared with the external soil, it is particularly suitable for large diameter open ended “monopiles” used to support offshore wind turbines. The application also includes the unique ability to be run in a “data driven mode”, whereby the Soil Resistance to Driving (SRD) is computed directly from input Cone Penetration Test (CPT) data.

Datamap

Described as ‘Dropbox on a map’, Datamap is a user friendly app for making geotechnical data accessible in with an intuitive and interactive mapping tool. Datamap can be used to freely access research data from several field test sites worldwide, including the Australian National Field Testing Facility, in Ballina. Please contact us to discuss a customised version of Datamp to securely store and share data exclusively within your organisation.

PIGLET

PIGLET allows analysis of the response of pile groups, under working load conditions, to provide stiffness and flexibility matrices for the pile cap (including torsional modes) axial, lateral and moment loading at the head of each pile, and profiles of bending moment and lateral deflection down selected piles. Piles are permitted to rake in any direction. The program can analyse piles of different length, as well as of different diameter.  Although the analysis is essentially elastic, the effects of non-linear axial and lateral response of individual piles may be quantified, including axial failure of piles that reach specified limiting loads.
