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。
Slope disasters often occur during the construction of highway in mountainous area, which will not only cause economic loss, but also bring great impact on construction safety and construction period. Combined with the practice of slope safety monitoring engineering in Hubei Yiba expressway, the work contents, technical methods and guidance significance for the slope safety monitoring during highway construction are introduced. On the basis of dynamic classification and evaluation of slope stability, combined with inspection and optimization during construction, monitoring and monitoring of high-risk slope are provided to provide analysis and early warning data for the stability of subgrade slope during construction and to do timely Out of more accurate judgments; station monitoring results also provide an important basis for the formulation of slope management programs and their comparison, it is worth learning from other similar projects.
