Research on bearing capacity characteristics of suction anchor foundation under torque loading in clay
This article investigates the ability of suction anchor foundations in clay to withstand horizontal and bending moment combined loads,as well as vertical and bending moment combined loads.First,the rationality of the finite element model is verified through numerical simulation tests.Based on the finite element method,a suction anchor foundation model with an aspect ratio of 1 is established.The bearing capacity characteristics of the suction anchor foundation under the combined action of horizontal load,vertical load and torque load are studied.The results show that under the action of torque load,the horizontal and vertical bearing capacity of the suction anchor foundation is significantly reduced.With the decrease of the horizontal load point,the ability of the suction anchor to resist the torque load shows a trend of first increasing and then decreasing.In the case of the combination of horizontal-vertical-torque loads,the decline trend of the ultimate bearing capacity of suction anchors increases significantly with the increase of torque loads.As the angle between the load direction and the horizontal plane increases,the bearing capacity of the suction anchor to resist torque loads tends to increase.
