Abstract Research purposes ： The methods for recognition and evaluation of landslide risk factors were researched by taking one landside as example and the main influence factors for the stability of one landslide were analyzed by using subjective evaluation method and fuzzy comprehensive evaluation method to find out the main factors that have the biggest influence on the target. According to the influence degree ,the risk factors were sorted to evaluate the risk factors, and the countermeasures for control of the risk were presented for providing the reference to the similar works.
Research conclusions ： The constructions of railway and highway, large -scale blasting，disordered mining and freely drainage and seepage of the water by residents were the main risk factors for the landslide. The size of the landslide was not well known and the most unfavorable sliding surface was not found ； The engineering measures were not taken perfectly. The risk of the landslide of the railway subgrade in the landsliding area along with the entire landslide was recognized as high risk level. According to the main risk factors of the landslide risk, the countermeasures of using anti -sliding pile，slope protection，building the ring intercepting ditch and filling the tension crack by clay soil were taken to ensure the safety of railway subgrade in the landsliding area.
