A series of physical model experiments of tsunami inundation over an idealized industrial site located in a coastal area were performed in this study. Two types of tsunami-like waves with markedly different characteristics were generated. The first was a single long wave and the second was a long wave with soliton fission (undular bore). This study measured the water surface elevation and velocity, as well as the pressures at several heights for some building and tank models that were installed over the coastal area. An experimental benchmark dataset for the tsunami inundations and impacts over a complex topography were produced. This investigation shows that a wide spatial variance of the maximum inundation depth was observed. This was caused by the effects of the surrounding structures, especially the blocking effects due to the structures. The location where the effects occurred depends on the blocking fraction as well as the Froude number of inflows. This study also investigates the relationship between the pressures and neighboring flow profiles. It was determined that under the inundation flow condition without soliton fissions and wave breaking, the maximum pressures can be predicted by the Asakura-type model from the neighboring flow profiles. On the other hand, for the bore condition, the Cross-type model is more appropriate for predicting the maximum pressures. The log-normal standard deviations of the differences between the measured maximum pressures and the predicted pressures are also shown. This information can be useful when performing a probabilistic damage analysis or analyzing the fragility of buildings.

本研究在位于沿海地区的理想工业场地上进行了一系列海啸淹没的物理模型实验。产生了两种特征明显不同的类似海啸的波浪。第一个是单个长波，第二个是具有孤子裂变（波状孔）的长波。这项研究测量了水面高度和速度，以及安装在沿海地区的一些建筑物和水箱模型在几个高度的压力。生成了海啸淹没和对复杂地形影响的实验基准数据集。该调查表明，观察到最大淹没深度的广泛空间变化。这是由周围结构的影响引起的，特别是由于结构引起的阻塞效应。影响发生的位置取决于阻塞分数以及流入的弗劳德数。该研究还调查了压力与相邻流动剖面之间的关系。确定在没有孤子裂变和波浪破碎的淹没流条件下，最大压力可以通过 Asakura 型模型从相邻的流动剖面预测。另一方面，对于孔条件，Cross-type 模型更适合预测最大压力。还显示了测量的最大压力和预测压力之间差异的对数正态标准偏差。在执行概率损坏分析或分析建筑物的脆弱性时，此信息非常有用。
