Dear plaxis,
When conducting a pseudostatic analysis of a slope, the factor of safety obtained is reasonable, however, the displacements are quite questionable.
Dear Abdirahman,
That is correct. In order to get more realistic results on displacements, you need to run a dynamic analysis.
What about the pseudostatic displacements? In case, someone wants to get a quick rough idea. Are they advisable?
Thank you very much for your reply. Is there a software that you offer, that can perform sliding block analysis?
As far as I am aware this is not possible with PLAXIS software.
I will add it as a request to our developers and research department for the future. Thank you!
Please check Rob's answer for SoilVision solutions.
Hello Abdirahman,
Bentley's SVSLOPE slope stability software based on the limit-equilibrium method offers Newmark's sliding block analysis to calculate permanent displacements. The SVSLOPE Theory Manual has some information on this method and is posted on this community here: https://communities.bentley.com/products/geotech-analysis/w/plaxis-soilvision-wiki/46681/theory-manuals---soilvision
For seismic methods, SVSLOPE offers pseudo-static coefficients, spectral pseudo-static, and Newmark sliding block, so along with PLAXIS finite-element analysis we can offer the full range of options.
thank you Rob Thode. Is there a trial version?
You can request a trial version here: https://www.bentley.com/en/about-us/contact-us/sales-contact-request?Area_of_Interest=90629&comment=I%20am%20interested%20in%20a%20free%20demo%20of%20SoilVision
If your organization has Bentley products under an ELS or E365 account you may be able to begin using SOILVISION.
