摘　　要：结合多座公路隧道现场监控量测工作,研究了服务于公路隧道现场施工的监测内容、监测方法以及现场采集数据的分析处理技术。对周边收敛量测、拱顶下沉量测、地表下沉及边坡位移量测等量测项目所得到的位移-时间曲线,进行了分门别类,并给出了适合现场及时反馈运用的数据分析处理方法。结果表明:现场监测的位移-时间曲线可分为正常型和非正常型,其中非正常型曲线又可分为跳跃型、突变型以及反常型等类型。结合工程实际,系统归纳了位移-时间曲线的正常型及非正常型中的跳跃型、突变型和反常型曲线的现场实用分析方法。Based on the site monitoring results of several highway tunnels, the contents and methods of site monitoring, and the analyzing methods for the collected data of highway tunnel construction were studied. The measuring curves of displacement with time of cortvergence, vault crown settlement and ground settlement were classified. The data analyzing methods were put forward for timely feedback in the construction process. The result shows that the curve of displacement with time can be divided into natural type and unnatural type. And the unnatural type can be subdivided into jumping type, breaking type, and abnormal type. The applications of those kinds of curves in engineering practice were presented. 7 figs, 14 refs.
