摘要2011年3月日本东北部发生海啸后，对基础设施损坏的现场调查发现，由于与海啸相关的高淹没深度和速度，许多燃料储存容器出现故障。观测集中在两个地区，即日本石卷市和日本女川市，测得的淹没深度分别高达6米和17米。观察到的故障模式包括：由于向内的流体静力或碎片撞击而造成的集装箱破碎、由于浮力升高而造成的系留故障以及由于事件期间施加的流体动力而造成的滑动故障。约束的丧失导致容器移动到其安全壳壁之外、燃料溢出和地面污染。基于观察到的容器故障、水位和估计流速的样本计算说明了观察到的需求和故障模式。最后提出了一种使燃料贮存容器损失最小化的改造机制。
AbstractField investigation of infrastructure damage following the March 2011, Tohoku, Japan, Tsunami uncovered failure of numerous fuel storage containers as a result of the high inundation depths and velocities associated with the event. Observations focused on two areas, Ishinomaki, Japan and Onagawa, Japan, where inundation depths of up to 6 and 17 m, respectively, were measured. The failure modes observed include: crushing of containers as a result of inward hydrostatic forces or debris impact, tie down failures as a result of elevated buoyancy forces, and sliding failures as a result of the hydrodynamic forces imparted during the event. The loss of restraint resulted in movement of the containers outside of their containment walls, fuel spillage, and ground contamination. Sample calculations based on observed container failure, water levels, and estimated flow velocities illustrate the demands and failure patterns observed. A retrofitting mechanism is proposed to minimize loss of fuel storage contai...
