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。
316 National Highway collapse and other geological disasters, seriously affecting the normal operation of roads and people’s lives and property safety. Based on the field survey of 316 Shirakawa-Shiquan section of National Highway (K1732 +100 ~ K1871 +500), the geological and environmental conditions of the area along the line were summarized and the formation conditions of collapse disaster were summarized. According to the mechanics mechanism and the scale of dangerous rock mass formation, it is concluded that the collapse along the railway line is medium-sized and the failure modes are cracking, slipping and dumping. Combining the relevant factors such as the scale of disaster and the degree of ease of governance, specific prevention and control measures are put forward for different modes of destruction.
