In order to study the impact of the collapse of a wind turbine on the buried pipeline, three conditions are explored. With the formula of penetrating power, the impact force and impact depth resulted from the wind turbine collapse are estimated for safety evaluation. The evaluation results show that if the impact is only from the wind turbine collapse, the pipeline is not damaged, but it is difficult to ensure the normal operation of the pipeline. If the damage is caused by the wing turbine with blades or only by blades, the downward penetrating force is so large that the pipeline is directly sheared off. Although the probability of wind turbine collapse is low, it is harmful to the pipeline and appropriate protective measures should be adopted.
