Four abandoned dreg sites along one Yunnan highway were taken as the engineering case in this paper.The quantitative analysis of stability of abandoned dreg site was carried out.The results show that the following measures that retaining wall,intercepting channel,and slope vegetation were taken for the abandoned dreg sites,which reduced the possibility of geological disasters like landslides,debris flow,and so on.By using of LizhengYanshi 7.0 software,the circular sliding method is adopted to calculate the smallest stable safety factor under normal operation conditions(natural conditions),and abnormal operation conditions(earthquake operating conditions,heavy rain conditions),the calculation results all larger than anti-slip stability safety factor,so four abandoned dreg sites are all in stable states at natural,earthquake,heavy rain working conditions.
