公路隧道监测数据异常的思考

隧道监测数据分析对于预报隧道安全是非常重要的,然而在分析过程中往往由于数据的缺失或监测项目选择的不合理导致对隧道安全预测不准,甚至得出相反的结论。建议在隧道围岩较差处同时布置变形和初衬混凝土内应力的量测项目,以提高预测的准确性。

Discussion on the Outliers of the Highway Tunnel Construction Monitoring

Monitoring data analysis is very important for the security prediction of the highway tunnel.In this process,missing data or the unseasonable monitoring items may result in the inaccurate security prediction,even the opposite conclusion.In order to improve the veracity of tunnel security prediction,the paper suggests detecting deformation property and internal stress of reinforced concrete primary lining insulation in case of tunnel surrounding rocks with poor geological conditions.
