Study on Dynamic Response of Gas Insulated Line Pipe Gallery Under Vehicle Traveling Loads
This study relies on the Huangbuling 500 kV transmission project to investigate the dynamic response law of gas insulated line (GIL) pipe gallery under vehicle traveling loads. A numerical model of GIL pipe gallery considering soil-structure interaction is developed using finite element software ABAQUS, and the effect of soil pressure on GIL is studied through static analysis. This study proposes a continuous step loading method for simulating vehicle traveling loads, and parametric analyses of different traveling directions and speeds are carried out to reveal the GIL’s dynamic response law in depth. The results show that the maximum stresses in the concrete and steel reinforcement cage of the GIL under soil pressure are located at the root of the right-side wall (both are less than the strength design value), and the maximum value of displacement is 6.556 cm occurs in the middle of the top plate. The maximum vertical acceleration, velocity and displacement responses under vehicle load occur at the top midpoint of the pipe gallery, while the maximum stress response occurs at the lower left corner. When heavy vehicle passes over the pipe gallery at different speeds, the peak acceleration, velocity and stress of the pipe gallery tends to increase with the increase of vehicle speed, while the peak displacement does not change significantly.
