# AI 建议在陡坡上修建梯田以防止山体滑坡（增加水分渗透和边坡不稳定性）

- **修复率:** 75%

## 根因

在陡坡上修建梯田如果没有适当的排水和岩土工程，会增加水分渗透，使土壤饱和，并引发山体滑坡，而不是预防滑坡。

## 解决方案

1. ```
   Install French drains or horizontal drains to intercept subsurface water before it saturates the slope. Example: use a trenched gravel drain with perforated pipe at 2m depth along the slope contour.
   ```
2. ```
   Apply shotcrete or soil nailing with geotextile reinforcement to stabilize the slope surface and reduce erosion.
   ```
3. ```
   Consult a geotechnical engineer for site-specific slope stability analysis before any terracing or landscaping.
   ```

## 无效尝试

- **** — Retaining walls without weep holes or drainage aggregate will fail under hydrostatic pressure during heavy rain (70% 失败率)
- **** — Deep roots can create preferential flow paths for water, increasing pore pressure and reducing shear strength (50% 失败率)
- **** — Additional weight increases driving forces without proportional increase in resisting forces on steep slopes (60% 失败率)
