隧道围岩监控量测与稳定性分析

摘要

以瑞金二隧道为例,在施工过程中先对隧道围岩进行监控量测,再采用EXCEL数据库和Boltzman函数对监控量测数据进行拟合分析.结果表明:量测结果较为准确,曲线拟合程度也较高,能够较好地反映隧道在施工过程中,拱顶下沉和水平收敛位移的变化情况.有利于施工者对隧道的稳定性做出止确的判断.%In this paper, relying on Ruijin three tunnels, carries on the monitoring gauging first in the construction process to the tunnel adjacent formation, then uses the EXCEL database and the Boltzman function to monitors the gauging data to carry on the fitting analysis. Analysis shows that The gauging result is more accurate, the curve fitting degree is also high, can reflect that well the tunnel in the construction process, the arch submersion and the level restraining displacement's change situation, is advantageous in the construction makes the correct judgment to tunnel's stability.
