A shallow SPC-reinforced foundation on Jolshiri reclaimed land may be a cost-effective solution for light-loading constructions like as duplexes, triplexes, or other low-rise residential buildings, among others. Common designers frequently decline to use SCP-based shallow foundations due to a lack of design competence and a lack of skilled labour/contractors. A thorough overview of the subject may instill trust in general foundation designers in this area.
In general, to improve the SBC, compressibility, lateral stiffness of existing ground laving loose deposits, Vibro-replacement or vibro-stone columns are proposed. To optimise the cost of backfill materials, instead of stone filling, compacted sand piles of appropriate gradation may be used.
To classify the fill material for SCP/ Vibro-floation construction, BROWN (1977 ) has defined a Suitability Number (SN)for Backfills which may be used in the design and evaluate the actual improvement factor that can be achieved at site.
