Help with modelling soil nail wall with SlopeW

[hlk]

Hi all! I am a geotechnical engineer in Auckland modelling various soil nail wall at the moment. Question is : why does SlopeW require the first point of the soil nails to be above the geometry where it is inserted? I can't see the difference in the results between starting above the geometry or on the geometry line.

Please help!!

Thanks!

The difference probably has to do with how the program finds the point of intersection between the surface geometry and the nail -

Sometimes roundoff errors in computers can wreak havoc. It's probably an effort to prevent divide by zero-type problems.

I know this doesn't answer you question but you will find the program SLIDE from Rocscience is much better for reinforcement in slopes than SLOPE/W
