I got a pipe within the embankment and need to calculate the lateral stresses due to the compaction during the embankment construction. I got two ways to do it:
1. Using ko to calculate the horizontal stress based on the vertical stress. But Ko value is not only dependent on the friction angle...
I noted that people would use different expressions for set criteria of driven piles. For example, 4 mm/blow or 40 mm/10 blows. Can I say they are the same? Thanks.
