Abstract
The population increase and construction development witnessed by the world in recent years and the exploitation of areas that may have unsuitable soil for constructing high rise buildings. Hence, it is necessity to develop a special type of foundation that can withstand large static and dynamic loads. The piled raft foundation system that depends on the soil-piles-raft interaction phenomenon is very important which was developed to increase the load carried capacity and reduce the settlement. Many types of weak soil are considered to be problematic which should be taken into consideration in geotechnical engineering. Therefore, the researchers studied the behavior of the pile raft system by experimental and numerical methods under static and dynamic loads to understand the mechanism of the load sharing between the foundation compositions as well as to reach the safe design regarding bearing load and settlement.
