高速铁路隧道施工中监控量测探析

Study on monitoring of high-speed railway tunnel construction

监控量测是在隧道施工过程中,对围岩和支护系统的稳定状态进行监测,通过拱顶下沉量测、格栅钢架内外力监测、锚杆轴力测试,将量测数据进行处理和分析,绘制时间-位移曲线,为喷锚支护和二次衬砌的参数调整提供依据,把量测的数据经整理和分析得到的信息及时反馈到施工中,以便根据检测数据灵活、及时地处理施工中出现的各种问题,确保工程质量和进度。

Monitoring in the process of tunnel construction is to monitor the stability of the surrounding and supporting system, and through the dome subsidencetest, the steel frame grille test both inside and outside and the bolt axial force test, measurement data will be treated and analyzed, rendering ＂time-displacement＂ curve and providing a basis for the anchor bolt-shotcrete support and the adjustment of the parameters of secondary lining. Data collected and information received are timely fed back to the construction, in order to flexibly and timely treat problems that appear in various issues to ensure project quality and progress.
