摘　　要：国道316崩塌等地质灾害频发，严重影响了公路的正常运营和人民生命财产安全。通过对国道316白河～石泉段（K1732＋100-K1871＋500）实地调查，总结分析了沿线区域的地质环境条件，归纳了崩塌灾害的形成条件。根据危岩体形成的力学机制和其规模，得出沿线崩塌为中型崩塌，并且破坏模式为拉裂、滑移、倾倒等3种。结合灾害规模和治理难易程度等相关因素，针对不同破坏模式，提出了具体的防治措施。The frequent geological disasters such as rock-fall in G316 affect the normal operation of the highway seriously, and threaten the security of people＇s life and property. The regional geological environmental conditions along G316 are analyzed and the forming condition of rock-fall disaster are summarized based on the investigation of Baihe-Shiquan Section （K1732＋ 100-K1871 ＋500） of G316. According to the dangerous rock＇s mechanical mechanism and its scale,they are concluded that rock-fall along G316 is medium scale, and its failure modes are ripping, sliding and toppling. Finally, in combination with the scale and the repairing difficulty of the disasters, some concrete prevention measures for all kinds of failure modes are put forward.
