Abstract: It is important to study seepage forms of confined water on translational landslide, which is helpful to accurately evaluate the slope stability and provides a reasonable theoretical guidance for studies on the disaster mechanism on translational landslide. Based on the variation law of seepage width of confined water, the seepage forms of confined water on slide plane of translational landslide are divided into the radiation flow and the non-radiative flow. According to different seepage forms, the translational landslide analysis models are established. Based on the theory of groundwater flow to canals, the water head line equation of confined water and the calculation formula of uplift pressure in different models are deduced. Furthermore, three kinds of uplift pressure distribution forms are put forward, and then the starting criterion of translational landslide is modified. Finally, based on a case of translational landslide, the law of slope stability under different forms of seepage is discussed.

Key words: translational landslide, confined water, seepage forms, uplift pressure, slope stability
