The rapid development of the domestic highway industry, the continuous expansion of the scale, followed by the maintenance of the road. Many roads are heightened on the original basis, so the height of the original guardrail cannot meet the protection requirements of the road. Therefore, this paper studies the ＂F-type＂ reconstruction scheme of the concrete guardrail in the maintenance project of a certain road; uses the finite element method to simulate and analyze the collision of the reconstructed guardrail, and uses the passenger car to collide. By analyzing the buffering, blocking and guiding functions of the guardrail. The results show that the reconstructed guardrail can meet the protection requirements of the guardrail.
