**Settlement Reducing Piles**

**What is settlement reducing pile in piled shafts and basements?**

As it may be understood from its name, pile reducing settlements is applied to solve the problem of differential settlement of shafts and basements slabs.
**Fig.2: Use of Piles to Reduce Differential Settlements**

**Why is the purpose of a pile reducing settlements in piled shafts and basements?**

When piles with the same length and diameter used to support basements and shafts slabs that carry uniform distributed loads, the deflection of the slab would be like dished shape.
At the beginning, the slab would support almost all the applied loads, but as the loading increases, the quantity of loads imposed on the piles increases progressively.
The loads exerted on the pile influence those located at the center and consequently central piles would experience greater settlement.
Due to the central pile settlement, the applied load would be redistributed through the slab to the stiffer piles around the perimeter and eventually greater loads will be exerted on these piles.
It is demonstrated that, after the redistribution of loads, around sixty percent of loads is supported by perimeter piles whereas nearly forty percent of applied loads are carried by central piles.
This differential settlement is a serious problem and need to be tackled properly. The utilization of settlement reducing piles is an appropriate answer for such problem. Not only does pile reducing settlements would solve differential settlements but also would result in a more economical construction.
