Abstract
Numerical optimization techniques are used widely for different engineering fields. But there are limited applications of this method in geotechnical engineering. However in this study, topology optimization of pile foundation for different site conditions and loading conditions is obtained through a finite element (FE) analysis study. The suitable topology of piles in foundation system offering minimum internal energy, i.e. maximum stiffness for a given fraction of material is studied. The study is also enhanced to the piles which are located in the soils prone to liquefaction. In the present study, the design methodology for cost optimization of construction of a pile group with a raft foundation is also presented through a case study. In the optimization algorithm, the raft dimensions, no of piles, pile diameter, pile length are taken as the design variables.
