摘要:
采用全球定位系统技术对宜(昌)—巴(东)高速公路大山坡隧道及高边坡进行监测.对大山坡隧道进行监测时,根据隧道特点等间距布置监测断面,选择隧道出口右侧监测断面,将监测点置于监测断面拱顶,安装位移计测定位移;对高边坡进行监测时,根据滑动范围选定测线和监测点,将3个监测点相应地布置在边坡体上,并布设变形监测基准网,实时获取隧道及高边坡各监测点的三维基准坐标.将处理分析所得的监测结果与数值模拟分析预测结果进行比较,其中隧道实际监测拱顶沉降为24.3 mm,数值模拟分析结果为22.5 mm,两者符合度很好,在监测预警系统中的评价等级为稳定.基于全球定位系统技术的山区公路隧道及高边坡监测技术具有选点灵活、自动化高、可全天候监测、定位精度高、监测数据可靠等优点.
Abstract:
Global positioning system technology was used to monitor Dashanpo tunnel and high slope of Yi(chang)Ba(dong) Highway.We arranged monitoring sections in equal distance based on the characteristics of Dashanpo tunnel,selecting the right side of the tunnel exit as monitoring section,setting up monitoring points in section vault and installing displacement meters.We selected measuring line and monitoring points according to sliding range of the high slope,emplacing three monitoring points and deformation monitoring basis network on the slope to access threedimensional reference coordinate of tunnel and slope monitoring points in real time.Comparing the monitoring results with forecasting results of numerical simulation analysis,the actual monitoring result of the tunnel vault settlement is 24.3 mm,matching well with the numerical simulation result of 22.5 mm,which is evaluated as stable degree in the monitoring and early warning systems.The monitoring technology of mountain road tunnel and slope based on the global positioning system technology has advantages of liberty in selecting points,allweather monitoring,high positioning accuracy and reliability of monitoring data.
