The acceleration data before and after the collision of drifted test body with a concrete wall due to a tsunami wave

although most fatalities in tsunami-related disasters are conjectured to be a result of drowning, injury risk owing to collision with other floating debris or fixed buildings has not been studied sufficiently. in this study, the impact force corresponding to the collision of a concrete block and drifting test body in a tsunami wave was experimentally investigated. the experiments were conducted using the large hydro-geo flume in the port and airport research institute, yokosuka, japan. the flume has length, width, and depth of 184 m, 3.5 m, and 12 m, respectively, with a piston-type wave-generator. in the experiment, a soft polyvinyl chloride (pvc) dummy and a pvc pipe with lids filled with water were employed as test bodies. two acceleration sensors were attached to the head and ankle of the km, and one sensor of the same type was attached at the top of the pvc pipe to investigate the impact of collisions.

尽管大多数海啸相关灾害中的死亡案例被推测是由于溺水所致，然而因碰撞其他漂浮碎片或固定建筑而造成的伤害风险尚未得到充分研究。本研究中，对混凝土块与海啸波中漂移测试体碰撞的对应冲击力进行了实验性探讨。实验在日本横须贺港和机场研究所的大型水力地文水槽中进行。该水槽长度、宽度和深度分别为184米、3.5米和12米，配备活塞式波浪发生器。在实验中，使用了软质聚氯乙烯（PVC）假人和装有水的PVC管道（配有盖子）作为测试体。在KM的头部和脚踝处各安装了两个加速度传感器，并在PVC管道顶部安装了一个同类型传感器，以研究碰撞冲击。
