摘　　要：隧道高地应力区的施工风险较高,但在该区域的监控量测技术尚未有明确的规范和标准,因此有必要探索隧道高地应力区的标准化监控量测技术。本文依托池祁高速公路某特长隧道工程,基于该隧道高地应力区和非高地应力区的监控量测数据,对比分析两处的拱顶沉降、周边收敛的变化规律;采用回归分析对监控量测数据进行分析,提出隧道高地应力区标准化监控量测技术及其数据处理方法。研究结果表明:隧道高地应力区监测量测结果与非高地应力区具有明显差异,应该根据隧道地应力分布情况加强高地应力区的监控量测;二次多项式对隧道拱顶沉降和周边收敛变化具有较好的拟合效果。The construction risk in the tunnel high ground stress area is high,but there are no clear specifications and standards for monitoring and measurement technology in this area.Therefore,it is necessary to explore standardized monitoring and measurement technology in the tunnel high ground stress area.Based on the monitoring and measurement data of a super-long tunnel project on the Chizhou-Qimen Expressway,and based on the monitoring and measurement data of the high and non-high ground stress areas of the tunnel,this paper makes a comparative analysis of the changes in the settlement of the arch crown and the peripheral convergence at the two places,uses regression analysis to analyze the monitoring measurement data,and proposes a standardized monitoring measurement technology and data processing method for high ground stress areas in tunnels.The research results show that there is a significant difference between the monitoring and measurement results in the tunnel high ground stress area and the non-high ground stress area,and the monitoring and measurement in the high ground stress area should be strengthened according to the distribution of the tunnel ground stress;The quadratic polynomial has a good fitting effect on the settlement of the tunnel arch crown and the peripheral convergence changes.
