Buried piping with landslide - 08/13/09 01:16 PM
I am working a study for buried pipeline in a landslide (depth 1.8m). We’ve got 60 displacement points according a monitoring survey on this area.
We want to determine critical areas of the pipeline.
I have proceeded in the following way:
1. Modeling design path (buried piping with both ends fixes, virtual anchor).
2. Apply the 60 displacement vectors over the pipe. The assumption is that pipe moves following the landslide
According my results, for step 1 there are not overstress, but for step 2, I ‘ve got huge values of stress (2000% !!!)
Would you advice us the following please:
How to model this phenomenon?.
What tools should I consider?
CNODES . How apply them in this case?
Please, help me
Regards,
Carlos
