Informationization of tunnel construction management is a trend nowadays. A displacement monitoring and analysis platform for highway tunnel surrounding rocks based on internet technology is developed by using PHP (Personal Home Page) programming language and in conjunction with Mysql data storage function and analysis principles of the least square method and regression model, so as to meet the informationization requirement of highway tunnel monitoring. By using the mentioned platform, the recording and regression analysis of the monitoring data of the highway tunnel, the assessment of the stability of the surrounding rock and the estimation of the final displacement of the surrounding rock and the secondary lining time can be realized. Furthermore, by using the mentioned platform, the technical staffs that are not at the site can obtain the monitoring data and analysis results of the tunnel so that they can make timely adjustment on the lining structure.
