Abstract:
In order to study the dynamic stability and seismic performance of the tower structure with its supporting system, and analyze the influence of the supporting structure on the seismic performance of the tower, a tower with its row-pile retaining wall in Xi'an was used as the research object, and its three-dimensional simulation model was established by the finite element software ABAQUS. The research results show that under the action of 0.2g(g is the gravitational acceleration)El Centro seismic wave, the lateral displacement of the supporting structure is divided into two time periods: reciprocating vibration of supporting structure at initial equilibrium position in 0 s≤t≤5 s; the displacement of the supporting structure increases sharply under the earthquake load in 5 s<t≤30 s, and the horizontal displacement of the back soil increases to 10 mm before failure. At 16 m of the pile, the dynamic bending moment reaches the maximum. When the amplitude of seismic is 0.1g, the maximum dynamic bending moment is 6 200 kN·m. When it changes to 0.2g, the maximum dynamic bending moment increases by 3 900 kN·m, and when it changes to 0.4g, the maximum dynamic bending moment increases by 9 100 kN·m. With the increasing of seismic amplitude, the dynamic bending moment increases more and more. The seismic amplitude has a great impact on the bending moment of the pile. The maximum horizontal displacement of each floor under the fortification intensity of 8 degrees after support is smaller than that before support. The maximum horizontal displacement under the frequent intensity is 2.27 mm less than that before support; the maximum horizontal displacement under the fortification intensity is basically the same as that before support; the maximum horizontal displacement under the rare intensity is 22.63 mm less than that before support, which reveals that the support structure effectively guarantees the seismic performance of the tower.
