Abstract: In the traditional study of tower pullout bearing capacity, the characteristic statistics are not comprehensive enough to obtain the hysteretic response characteristics of transmission line tower bearing mechanics. In order to quantitatively analyze the pullout bearing capacity of high-voltage transmission line towers in soft soil area, a numerical simulation method for the pullout bearing capacity based on the joint characteristic analysis of load-stress yield response is proposed. The hysteresis response characteristics of bearing mechanics were analyzed by using hysteretic optimal control method with different configurations. To extract the statistical characteristics, combined with electrical line tower pull-out skeleton curve, stiffness degradation curve, the bearing capacity of residual deformation distribution curve of conjoint analysis method, established numerical fitting the bearing capacity of transmission line tower pull-out model, through the load - joint characteristics of yield stress response analysis, the simulation of high voltage transmission line tower in soft soil area of uplift bearing capacity. The simulation results show that the numerical simulation method for the pullout bearing capacity of the high-voltage transmission line tower in the soft soil area has high accuracy, strong quantitative analysis ability and ideal applicability.
