结合特大断面公路隧道——广州龙头山双向8车道隧道公路工程实例,根据特大断面的力学行为及变形特点,以及工程勘察所揭露的围岩特性,分析并确定了龙头山特大断面隧道的监测内容和监测点的布置方式,利用自行研发的隧道远程自动监测系统对监测断面的拱顶沉降及锚杆轴力进行量测,最后对龙头山特大断面施工运营期间的拱顶沉降及锚杆受力特点进行分析总结。该工程系国内首次应用基于Web(Internet)及GSM中GPRS的无线远程传输方法 +智能无线自动综合监测系统,实现了对隧道运营期的远程自动监测,为今后特大断面隧道远程自动监测提供了参考。
According to the engineering example of two-way 8-lane tunnel in Longtoushan Highway, an extremely large section highway tunnel, according to the mechanical behavior and deformation characteristics of the large section and the surrounding rock characteristics exposed by the engineering survey, the monitoring contents of the Longtoushan section tunnel are analyzed and confirmed And the layout of the monitoring points, the use of self-developed tunnel remote automatic monitoring system of the monitoring section of the vault settlement and bolt axial force measurement, the last section of the faucet during the operation of the large section of the vault settlement and anchor force Features for analysis and summary. The project is the first application of wireless remote transmission method based on Web (Internet) and GPRS in GSM + intelligent wireless automatic integrated monitoring system for the first time in China, realizing remote automatic monitoring of tunnel operation period and providing reference for remote automatic monitoring of large-section tunnel in the future. .
