摘要
采用数理统计理论,以沪昆客专高家屯隧道监控量测结果进行分析。结果表明,隧道净空收敛和栱顶沉降与围岩级别、时间因素和施工因素等呈正相关,并与隧道围岩级别相关性最好,研究结果可作为石灰岩地区岩溶隧道施工方法和支护方案选择的重要参考依据,对确定合理的隧道二次衬砌时间具有重要的应用价值。
This paper used the theory of mathematical statistics to analyze the monitoring and measuring results of some tunnel.The results showed that tunnel clearance convergence and crown settlement were positively correlated with rock level,the time factor and construction factors,and had the best correlation with the tunnel surrounding rock classification.The research results can be used as an important reference for the construction method and the selection of the supporting scheme in the limestone area,which has important application value for determining the time of the second lining of the tunnel.
