Structures constructed on soft soil are considered to be at risk due to its low shear strength and high compressibility. Thus constructed structures on soft soil are designed according to its undrained shear strength, representing the bearing capacity of the shallow foundation in the short term conditions, which varies with time under the applied load. The bearing capacity in short term conditions is limited because of the generation of excess pore water pressure as soon as the initial loads are applied. Hence in this paper, the bearing capacity of shallow foundations on soft soil is studied by varying the time and the applied loads. The shallow foundation is subjected to a series of applied loads and consolidation phases to study the effect of aging. The study is investigated by means of finite element analyses taking account of consolidation processes in the ground, in which the soft soil is modeled using the Soft Soil model. The analysis is performed by finite element package of Plaxis program. The numerical analysis clears that the bearing capacity in the long term conditions is enhanced and has a significant enhancement following each consolidation phase when compared with the short term conditions.
