I have a site with soft soil. The site needs preloading with wick drains before building the MSE wall. I am recommending 90% consolidation before unloading and the construction of the MSE wall. Since there will be preloading and unloading at the site my thinking that the rebound at the site will be negligible since the time between the unloading and the construction of the MSE wall will be short (say less than 40 days with 90% prior consolidation). In addition, I think that during the construction of the MSE wall, most of the rebound will transfer to instant (elastic) settlement and will not show as "consolidation" settlements after building the MSE wall. Am I thinking right? Any thoughts in this regard? How to calculate the rebound if you have 90% consolidation? Thanks all.
