| 摘 要： | 指出在黄土滑坡、地裂缝、黄土洞穴等地质灾害发生发展过程中下渗重力水所起的作用最为关键,对下渗重力水的基本特点进行了全面归纳总结。以黄土洞穴灾害为例,将黄土暗穴形成过程中黄土地层地表径流的下潜模式概化为渗透重力水漫渗型下潜模式、地表径流集中灌入下潜型模式、渗透重力水沿优势渗流通道集中下潜型模式以及混合灌渗集中下潜型模式等4种基本模式。

| Abstract: | The basic characters of gravity water are generalized.,The authors suggest that the gravity water is one of the key factors of the hazards such as loess slope slides,ground fissures and loess tunnels.Through example study such as loess tunnel hazard,the modes of surface runoff are generalized as four basic modes:gravity water evenly infiltration mode,surface runoff injection mode,gravity water injection through dominant path mode and multiple mode. |

| Keywords: | Loess layer Ground water styles Surface runoff Mode |
