Review on the used granular cushion in load sharing of unconnected piled rafts in clayey soils under earthquakes Available to Purchase

Over the past few decades, interest has grown about the role of the piled raft structure in soils. A structural fill cushion separates the piles from the raft in the form of an unconnected piled raft base (UCPRF). Given the advantage of this structure, the load is dispersed between the raft and the piles by the cushion. The cushion serves as a load redistributor between the raft and the piles. A new type of foundation called Disconnected Piled Raft (DPR) with a layer of granular cushion between raft and piles which acts as soil stiffeners is suggested by sever-al studies. The current paper summarizes past available research articles on The used Granular Cushion in Load Sharing of Unconnected Piled Rafts and offers various conclusions and recommendations. the results show the cushion layer plays a critical role in enhancing load distribution, managing settlement, and improving the overall performance of various foundation systems. Its properties, such as thickness and stiffness, interact with other factors to influence load transfer mechanisms and foundation behavior. Proper design and optimization of the cushion layer contribute to more efficient and stable foundation systems.
