柔性测斜仪在公路边坡自动化监测中应用研究

为了深入理解营运高速公路高边坡深部位移的变形机理,更好地进行防灾减灾工作,使用阵列式位移传感器(SAA)对营运高速公路高边坡进行深部位移动态监测,并同时使用人工测斜仪进行数据对比分析。通过4G网络建立了无线数据传输系统,实现对边坡体全天候监测。试验结果表明:在营运高速公路高边坡深部位移监测中,使用阵列式位移传感系统与无线数据传输系统进行监测,不仅能够实时监测到边坡体深部位移的变形情况,还能判断出滑移面具体位置。相较于人工测斜仪监测,阵列式位移传感系统测量精度和效率更高,在公路高边坡监测中具有广阔的发展前景。

Research on Application of Flexible Inclinometer in Automatic Monitoring of Highway Slope

In order to understand deeply the deformation mechanism of deep displacement of high slope of expressway in service,and to better prevent and mitigate disasters,the array displacement sensor(SAA)was used to dynamically monitor deep displacement of high slope in service expressway,and artificial inclinometer was used to compare and analyze the data.Wireless data transmission system is established through 4G network to realize the all-weather monitoring of the slope body.The test results show that the array displacement sensing system and wireless data transmission system can not only monitor the deep displacement of the slope body in real time,but also judge the specific position of the slip surface in the deep displacement monitoring of the high slope on the expressway.Compared with manual inclinometer monitoring,the array displacement sensing system has higher measurement accuracy and efficiency,and has a broad development prospect in highway high slope monitoring.
