| 摘 要： | 饱和渗流是岩土体失稳的重要因素。叙述了渗流产生的消极破坏力“浮力”和积极破坏力“渗透力”。较详细地讨论了渗流各力之间的相互转换关系及其在管涌滑坡问题中的正确应用；并特别推荐引用渗透力计算滑坡问题具有简便、精确的优点。并指出了在计算中和设计规范中引用渗流力方面的误解。

| Abstract: | Saturated seepage flow plays an important role to cause instability of soil-rock mass. The destruction forces, the passive “buoyant force” and the active “seepage force” induced by seepage are described. The mutual converted relation between seepage forces and boundary water pressures as well as their correct application to piping and landslide problems is discussed in detail. Using seepage force instead of boundary forces in landslide computation is recommended for its simplicity and accuracy. Misunderstanding about seepage force used in computation and design code is pointed out. |
