摘要： 边坡灾害在山区高速公路工程施工过程中经常发生，既会造成经济损失，也会给工程施工安全和工期带来较大影响。结合湖北宜巴高速公路边坡安全监控工程实践，介绍了针对高速公路施工期间边坡安全监控的工作内容、技术方法以及对工程建设的指导意义。在边坡稳定性动态分类与评估的基础上，结合施工期间的巡查、优化，并对高危边坡进行设站监测，为路基边坡在施工期间的稳定性提供分析和预警资料，并及时做出较为准确的判断；设站监测成果也为边坡治理方案的制定及其比选提供重要依据，值得其它类似工程借鉴。

Abstract: Landslides and slope instabilities are the common hazards in the construction of highways in the mountain areas. The consequences of the hazards result in not only the economic loss but also adversely affect the construction safety and the construction schedule. The highway slope stability monitoring program for the YiBa highway construction is presented in this paper. The monitored items, technical approach as well as the purpose are introduced. The monitoring results combined with the site visits during the construction, real time slope classification and evaluation, provide a forecast of the potential slope instability and can be used as the assistant to the decision making. The monitoring results can also be used as the criteria for various slope stability mitigation techniques.
