In this study, an innovative idea of using a plane circular raft surrounded by a water tank is tested numerically using finite element simulations and compared with a conventional piled foundation concerning the geotechnical behavior. Cost comparisons are done for two foundation solutions. An observed soil profile found in Port-Said region in Egypt is used. The soil profile is implemented in the FE softwares Abaqus and Elpla to evaluate these types of foundations on the mentioned type of soil. In terms of settlement and tilting it is shown that there is a good effect of using a water tank surrounding the ordinary circular raft for the actual soil profile in the Port-Said region. For the cost issue, the analysis was carried out to calculate the whole foundation cost for a circular raft surrounded by a water tank and also for a piled raft. It is shown that using the new foundation system will give a decrease in the initial foundation cost by 28% compared to using a piled raft with a pile length equal to 24 m. The effect of dynamic loads was also investigated and the results showed that the tower-foundation-soil system, using a circular raft surrounded by a water tank, successfully avoids resonance through the rotor excitations.
