Abstract Research purposes: The stability analysis of the railway rock slope is one of the most concerned problems in railway construction in mountain area． In recent years，the engineering accidents caused by the unstability of the bedding rock cutting slope have occurred frequently because the position of the sliding surface can ＇t be accurately allocated due to being short of the scientific and rational evaluation method． This paper presents a analysis method for the stability of the sliding body along the different rock boundaries and longitudinal cracks．

Research conclusions: A bi － direction searching model based on plane coordinate system is established． This model considers the geometric features of the multiple level platforms of the cutting slope and the rock stratum attitude，and it can be used to analyze the hidden sliding body one by one and search for the minimum safety coefficient about slope stability． In addition，in order to improve the analysis efficiency of the stability of the rock cutting slope，an professional software is developed by using C # programming tools to realize the automatic searching for the bi － directional structure surface of the bedding rock slope．

Key words： bedding slope bi － directional searching stability model
