Would it be possible to reduce embankment settlement at the embankment / abutment interface by injecting lime deep into the underlying foundation ground, a deep soft delta formation? I am thinking of injecting the lime using high pressure compressed air. There would be no way to spread and mix the lime except if it permeated outward which would be only a short distance except maybe along a silt or sand layer within the clay bed. If so, this would end up as kind of lime pile, requiring many in a grid pattern. If this is possible it should strengthen the deep soil and reduce the settlement.
Lime stabilization with deep injection :
yes definitely it is possible that the embankment settlement can be reduced at embankment junction by lime stabilization with deep injection
The process of injecting a lime slurry into the subsurface up to some depth of some feet it is one of the innovative and comparatively very good technique for an engineer as well as for labour.
The main purpose of constructing climb up to some depth is to fill voids with a chemical compound
