Behaviour of Skirted Foundation Under Different Loading Conditions Using FEM Approach
In case of foundation design for structures like Wind Turbine, there is a need to satisfy bearing capacity and settlement criteria to counter moment induced by environmental loading in addition to general loading. Foundation with skirts around the circumference are now considered to be a viable foundation alternative for a variety of offshore and onshore structures to satisfy the overall stability and to limit the dimensions of the foundation. By providing skirted foundation, the soil in between the skirts gets confined and increase the bearing capacity of same soil. Thus it will be very useful in diminishing the cost of stabilization of the soil. The present work focused on the 3D FEM analysis of octagonal raft foundation with and without skirts using Plaxis3D. The studied parameters incorporated the influence of loading conditions, length of skirts (L), and spacing of skirts (D) on bearing capacity and settlement of both the foundation condition. The enactment of a simplified skirted foundation model under vertical and moment loading is investigated for three skirts configuration with varying length of skirts and the stiffness value (E) of soil to check the efficiency of skirts and compared with non-skirted foundation. The results shows that the reduction in differential settlement and rotation due to moment loading with increase in length of skirts (L). Thus FEM analysis introduced in this investigation helped in better understanding and identifying the failure pattern of octagonal raft foundation with and without skirt.
