Abstract On August 31 to September 2，2014，affected by an extreme rainfall，deformation of a super large slope at Caijiaba in Yunyang County was found to increase rapidly. Hence，this paper employs the multi-source data，namely historical records，satellite remote sensing image，UAV aerial photography and field survey data，etc.，to determine the scope，characteristics and environment of the landslide. Afterwards，drilling，trenching，well exploration and geophysical exploration，indoor and field experiments were carried out to determine the landslide area formation，sliding zone and physical and mechanical properties. The failure mechanism of landslide was discussed and the slope stability was analyzed. The results show that Caijiaba slope is a large multi-stage flat sliding slope induced by rainfall. There are four slip surfaces(zone)，namely the soil sliding zone，shallow rock sliding zone，middle rock sliding zone and the deep rock sliding zone. The status quo of the sliding deformation is controlled by soil sliding zone，shallow rock sliding zone and middle rock sliding zone. Earlier stage of landslide accumulation and landslide slip surface(zone) provide the material basis for the status quo of deformation. The rear edge crack of front sliding zone provides the space for the rear sliding zone to move. Under heavy rainfall，a wide range of deformation and failure may be induced, and local sliding is likely to be caused. Stability analysis shows that the landslide is in a basically stable to steady state. However，the stability under heavy rainfall is significantly reduced. The stability of the slope has generally been declining to the unstable to basically stable state, and local sliding may occur.

Key words： slope engineering multi-source data rainfall huge landslide at Caijiaba failure mechanism stability analysis
