Abstract Red-bed soft rocks with gentle dip angle，which comprise sandstone，mudstone and shale，are widely distributed in Wumeng Mountain Area，and numerous landslides are easily triggered by soft and hard interbedded rocks. In this study，Huashengdi landslide was studied using geological investigation and centrifuge tests，which aimed to explore geological evolution and sliding process affected by rainfall infiltration. According to the study results，red-bed soft rocks have geomechanics properties of easy softening，creeping，weathering and disintegration. The interaction of rock damages and water softening，which has been found to be the main factor for affecting the stability of red-bed soft rock slope，where deep cracks are formed by geological action，such as earthquake，valley incision，etc. Meanwhile，the cracks promote the rainfall infiltration，resulting in saturated water softening at the sliding zone，quick creep deformation and even sliding. It may eventually give rise to the damage due to hydrodynamic instability in heavy rains. Geological evolution and sliding processes of landslide are divided into four stages，including the initial status，damage and degradation of rock mass，water softening and creepage，and instability triggered by rainfalls. The study results serve as the basis for analyzing the stability mechanism and engineering improvement of rainfall-type red-bed soft rock slopes.

Key words： slope engineering red-bed soft rock landslide geological evolution sliding mechanism centrifugal tests
