Impact of transmission tower collapse on adjacent buried natural gas pipelines based on LS-DYNA
To study the impact of high-voltage transmission tower collapse on adjacent buried natural gas pipelines,a 110 kV high-voltage transmission tower and a gas transmission pipeline that are cross laid were studied.LS-DYNA software is applied to simulate and calculate the stress,displacement,and moving velocity of the pipeline caused by transmission tower collapse.The results show that with the protection of the pipe duct,the maximum equivalent stress,the maximum total displacement,the maximum total pressure,and the maximum velocity are reduced by 26.89%,48.6%,30.61%,and 44.57%respectively.The protective effect is very remarkable.
