The effects of road pavement influence on stability of road landfill by rainfall infiltration were analyzed in this study. A typical landfill model were selected and seepage behaviour was analyzed by finite element method. According to application availability of road pavement, the model were divided by nothing pavement, whole pavement, and portion pavement. And landfill height, rainfall condition, slip surface depth, and change of pore water pressure were analyzed. The research result was as followed. When landfill height was 5m and nothing pavement, increase of pore water pressure was showed remarkedly after rainfall end, but in case of the whole pavement and portion pavement was decreased. In case of the landfill height was 10m, 15m, the pore water pressure change by pavement availability was displayed resemblant change nearly. During rainy season, the stability of landfill was received an influence that landfill height 5m was below according to pavement condition, but in the case was more than 10m, the efect was slight. The depth of sliding from slope surface was showed form that increase according to landfillb height, but the relation of pavement condition about sliding depth could not be divided hardly.
