Abstract Research purposes: Rock pile is widely distributed in the mountain area in the southwest in China, and the mountain railway has to cross the rock pile area. The analysis and evaluation of the development stage and the stability of the rock pile and their influences on the engineering are crucial to the railway alignment and choice of the engineering measures. In this paper, compared with the actual works，the evaluation is made on the stability of the Faqi huge rock pile along the Zhijin-Bijie Railway and its influence on the engineering，and the corresponding measures are presented for reducing the disturbance to the rock pile.
Research conclusions: (1) Most of the huge rock piles have been formed for a long time and they are in steady state because they have obtained their stability or equilibrium. (2)The evaluation of the rock pile is crucial to the reasonable railway alignment and the reasonable selection of the engineering measures.(3)If the rock pile is in steady state，the railway can cross the rock pile area in appropriate position by taking the reliable engineering measures. (4)When the rock pile is still in stable state，it is unnecessary to do the overall reinforcement to the rock pile.(5)The deep study on the rock pile presented in this paper is good for saving the engineering investment and has a certain reference significance to railway alignment.
