Slake
Analysis of soil liquefaction under seismic loads
Slake is a software package designed to analyse the risk of soil liquefaction under seismic loading, based on the analysis of in situ test data.
Slake enables this risk to be quantified by applying the NCEER semi-empirical method, based on the analysis of in situ SPT and/or CPT(u) tests.
The calculation of safety factors is supplemented by the determination of additional indicators of induced effects, such as post-liquefaction settlement of saturated soils and the liquefaction potential index (LPI).
Key strengths
- Application of the NCEER reference method (Youd & Idriss, 2001) for calculating safety factors against the risk of liquefaction.
- NCEER/CT45-AFPS2020: Implementation of a supplementary calculation option NCEER/CT45-AFPS2020 in accordance with the recommendations of the AFPS Technical Report “Assessment of the risk of soil liquefaction due to earthquakes – Practical knowledge and applications to geotechnical projects”, to be published in 2021
- Ability to perform analyses based on the processing of CPT(u) and/or SPT test data
- A user-friendly interface that makes it easy to navigate between different surveys and includes tools for importing, exporting and converting units on the fly
- User support provided by numerous help prompts, continuous visual validation of input data, and wizards for the automatic definition of certain assumptions in accordance with current standards (acceleration/magnitude pairs, additional tool for soil sensitivity to liquefaction)
- Seamless implementation of calculations with full control over all modelling parameters and assumptions
- A powerful graphical tool for displaying survey data and calculation results, including the configurable overlay of analysis results from different surveys and the projection of planar representations of key results (kriging interpolations)
- Generation of customisable calculation reports for the presentation of input data and analysis results
