摘要： 危岩体落石一直是影响周围居民安全的重要问题，目前对于落石的轨迹分析主要是经验公式与运动学分析法相结合。经验公式具有一定的局限性，因此在对万安危岩体的分析中，运用反演法对坡面的摩擦系数进行计算，同时归纳了落石在反弹斜抛过程中的运动轨迹公式。通过运动学公式和归纳公式，结合万安街道地区危岩体边坡的地形特点，对落石的轨迹进行了分析，描述了落石的运动轨迹，并在此基础上提出了防治的建议。

Abstract: Unpredicted rock falling has always been an important threat affecting the safety of adjacent residents. At present, the analysis of the trajectory of rock falling is mainly a combination of empirical formulas and kinematic analysis methods. The empirical formula has major limitations. Therefore, in the analysis of Wanan Street rock fall potential, the inversion method is used to estimate the friction coefficient of the rock slope, and at the same time, the trajectory formula of the falling rock during the rebound and oblique throwing process is summarized. Throughout the use of existing kinematics formulas and induction formulas, combined with the topographical characteristics of rock slopes with rock falling potentials in Wanan Street area, the trajectory of rock fall is analyzed, the track of rockfall pattern is described in the paper. Rockfall mitigation and prevention suggestions are also proposed in the paper.

Key words: hazards of rock, rock falls, trajectory of falling rock ,
