# AI 建议在房屋周围建造沙袋屏障以阻挡海啸波浪（高度不足和结构失效）

- **修复率:** 78%

## 根因

沙袋屏障是为缓慢上升的洪水设计的，无法承受海啸的巨大静水力和动水力；波浪会漫顶、冲垮或冲走沙袋，碎片会将沙袋变成抛射物。

## 解决方案

1. ```
   海啸警报发出后立即疏散到高地。不要留下保护财产。如果水平疏散不可能，垂直疏散到淹没区以上加固的混凝土建筑是唯一安全的选择。
   ```
2. ```
   如果必须就地避难，请移动到建造良好的多层钢筋混凝土建筑的顶层，远离窗户。不要使用沙袋。
   ```

## 无效尝试

- **Use multiple layers of sandbags stacked in a pyramid shape** — Pyramid stacking still lacks structural integrity against lateral wave forces; the base may scour out, and wave momentum dislodges upper bags. (90% 失败率)
- **Reinforce sandbags with rebar or wooden stakes driven into the ground** — Stakes provide minimal anchoring against the lifting and dragging force of a tsunami; wave debris can snap stakes, and the entire structure can fail catastrophically. (82% 失败率)
- **Place sandbags inside the house near doors and windows instead** — Interior barriers do not prevent water entry; they only trap water inside, increasing structural load and drowning risk. Tsunami water enters through every opening. (95% 失败率)
