As the safety hazard of the wind turbine collapse on the buried pipeline threatening the ChinaMyanmar pipeline project, three scenarios were induced based on four common failure modes of wind turbine collapses. By using the formula of penetrating power, the impact force and impact depth resulted from the wind turbine collapse were estimated. The change patterns of stress and strain parameters of the pipeline u was analyzed. The result of safety evaluation was given. The results show that if the impact is only from the wind turbine collapse, the pipeline is not damaged even with a large ovality change of the pipe, but it is difficult to ensure the normal operation of the pipeline; if the damage is caused by the wing turbine and blades or only by blades, the downward penetrating force is so large that the pipeline will be directly sheared off. Therefore, it is suggested that the connection strengths of blades above the pipeline be appropriately strengthened, in order to prevent the incident of blades to damage the pipe and shear off the ChinaMyanmar gas pipeline from happening.
