在目前的实践中，近水结构物的碎屑场冲击载荷通常来自(1)罕见的案例，(2)简化的解析方程，(3)从业人员的经验。通过在多个规模和条件下对海啸引发的碎片场影响进行先进的数值模拟，我们现在正在打造一种建模方法，以处理更广泛的情景。扩大的案例具有特征，具有随机表现的混乱性质。这些分析工具有可能加强ASC7准则的基础，并涵盖守则中尚未说明的事件。
In current practice, debris-field impact loading for near-water structures is usually derived from (1) infrequent case histories, (2) simplified analytical equations, and (3) practitioner experience. Via advanced numerical simulation of tsunami-driven debris-field impacts at multiple scales and conditions, we are now forging a modeling approach to address a wider range of scenarios. Broadened cases are characterized, with chaotic natures expressed stochastically. The analytical tools have the potential to strengthen the basis of ASCE 7 guidelines and to encompass events not yet described in the code.
