道路防護柵の衝撃エネルギー吸収に関する実験的研究

Abstract

The guard fence in the road is one of important equipment that can prevent vehicles from running outside the road when they have deviated from the normal direction. It also can enhance the security of passengers, decreasing the damage of the vehicles and goods on it. So we should ensure the guard fences designed that have enough strength to avoid rupture form the shock by high-speed vehicles and also have enough plasticity to absorb shocking energy for lightening the damage of the people and vehicle. At present, the replacing and repairing of guard fences cost a great deal of money and time and effect the daily traffic badly because it is easily damaged. The purpose of the thesis is to develop a new type of guard fence that can satisfy the request of strength and plasticity and can be replaced and repaired easier and cheaper.
