高速公路边坡自动监测与稳定性分析

Automatic monitoring and stability analysis of expressway slope

为了研究自动监测对边坡稳定性判断的准确性,以汉十高速某填方高边坡为例,采用GNSS位移自动监测手段对该边坡进行监测,通过实时监测数据分析监测点累积位移—时间曲线和位移速率—时间曲线,判断边坡的稳定性,辅以现场巡查进行验证,再通过稳定性计算进行定量评价,结果表明,边坡自动监测手段能较准确的判断边坡的稳定性,其可作为高速公路边坡灾害预防的一种有效手段。

In order to study the accuracy of automatic monitoring for slope stability judgment, taking a high slope in Hanshi expressway for example, adpot GNSS displacement automatic monitoring method to monitor its surface displacement, analyze cumulative displacement-time curve and displacement rate-time curve by real-time monitoring data to judge its stability validated by on-site inspections and stability quantitative calculation. The result shows that automatic monitoring method can accurately judge the stability of the slope, which can be used as an effective means of disaster prevention in expressway slope.
