| 摘 要： | 含碎块石土质边坡中常发育有地下水排泄管道，他们控制地下水水位上升，对保持边坡稳定十分重要。当坡脚开挖或坡体堆载时，会破坏管道状地下水排泄系统，从而导致地下水水位升高，使潜在滑面上的孔隙水压升高，最终导致滑坡的发生。以小旦滑坡为例探讨这类边坡的变形破坏机制。 |
| 关 键 词： | 土质边坡 滑坡 地下水排泄系统 孔隙水压 变形破坏机制 |

| Abstract: | Pipe drainage of groundwater are often developed in the pebbly clay slopes and are important in restricting groundwater level rising and in keeping slope stability. Cutting at slope toe or loading on slope surface may destroy the pipe seepage system and make ground water level rise obviously. As a result, the pore water pressure on a potential slip surface will rise and a landslide may take place.,The Xiaodan landslide is studied as an example in the paper. |
| Keywords: | pebbly clay slope landslide mechanism underground seepage system |
