concrete wall sliding and OT checks 3

[pelelo]

Hello,

I ran a global stability analysis for a concrete retaining wall using SLOPE/W.

As usual, other than global stability, we need to check Overturing and sliding.

I was wondering If it is advisable to obtain the acting forces on the WALL from SLOPE-W analyses OR do i need to run another software (such as PYWALL) which generates earth pressures and grab from there the forces to run OT and sliding?

Please advise.

You only input strength parameters in Slope W. I dont think you input Ka, Ko etc.

And even assuming that the software internally calculates Ka, Ko etc, is wrong I believe as I dont think OCR is in input. OCR is also a parameter required for determining earth pressures.

You dont need software, an hand calc or spreadsheet is all you need for OT and sliding checks.

Thanks a lot.

It makes sense.

Slope/W is global stability only, you need hand calcs or another software package e.g. geo5 (

You do not need any software to generate earth pressures and check for OT and sliding stability. You can do hand calculation or develop Excell spread sheet .

Pls look attached doc. for more info.



Use it up, wear it out;
Make it do, or do without.
