Research methods: Based on one loess landslide of a high embankment of Baoji-Zhongwei Railway, the exploration is made on the method of determining the location of slide face through comprehensive consideration of the liquidity index, elastic index, water content, joining face between fresh and old soils, slope crack and bulging control spots. Based on the data of survey, the most unfavourable slide face can be found out through forming a series of fold lines with the different formulas, determining arc slide faces of every group with the slope crack and bulging control spots and making analyses of single element and multiple elements.
Research Conclusions：The construction practice of adopting anti-sliding pile based on the calculated pushing force of the most unfavorable slide face shows this analysis method is feasible for the homogenized soil body which had a small wriggle and deformation without obvious overall displacement and was difficult to determine the position of sliding face with the complicated surface phenomenon.
