基于概率统计下白马隧道监控量测预警阈值研究

Research on Warning Threshold of Monitoring and Measurement of Baima Tunnel Based on Probability Statistics

隧道施工监测及信息反馈被认为是隧道施工过程中必不可少的环节,但目前现行规范对部分测试项目的预警阀值未明确规定,因此寻求一种切实可行获得预警阈值的方法极为必要。文章以九绵高速公路白马隧道为背景,从概率统计角度对已有监测预警数据进行统计分析,总结给出建议预警阈值,为白马隧道后续施工及其他类似工程建设中监控量测预警管理提供借鉴。

Feedback of tunnel construction monitoring information is considered as the indispensable link in the tunnel construction process.However,the current standard has not clearly defined the warning threshold for some test items.Therefore,it is necessary to find a feasible method to obtain early warning threshold.Based on the Baima Tunnel of Jiu Mian Expressway,this paper analyzes the existing monitoring and early warning data from the perspective of probability and statistics,summarizes the proposed warning threshold,and provides reference for the monitoring and early warning management of Baima Tunnel construction and other similar projects.
