Abstract Research purposes: With the implement of strategy of developing the west，the railway construction in western mountain area is speeded up．The landslide induced by construction increases．Landslide belongs to unfavorable geology disaster with huge impact on the construction．Due to the insufficient understanding of the landslide，there are many badly damaged accidents occurring after the completion of construction．Thus a correct understanding of landslide is very important to making a correct evaluation of the stability of landslip．Summarizing the experience，analyzing the forming mechanism and causes for the landslip induced by construction of Boerbosong Bridge and offering the treatment measures are very significant to design and construction of the railway and ensuring the traffic safety．

Research conclusions: The principle of”Prevention First”should be followed to route selection in mountain area．It is unavailable for”Big Cut and Big Filling”in bedding slope area．because the”Big Cut and Big Filling”will destroy the stability of the mountain．The temporary support should be strengthened when constructing in bedding slope area．The route should avoid or bypass the bedding slope area．
