文章详细介绍了地下工程盾构区间段的工程概况和工程地质条件以及现场变形监测情况。根据监测数据对各断面沉降槽宽度系数进行了统计分析与计算;对比了不同沉降槽宽度系数经验计算公式计算结果与实测统计结果之间的误差,从中选取了适用于本项目特点的沉降槽宽度系数计算公式。在此基础上提出了沉降变形的预测计算公式,将计算公式的计算结果与实测数据进行了对比分析,结果表明各个断面监测点的实测值与计算值基本吻合。
The article introduces the engineering general situation, engineering geological conditions and on-site deformation monitoring of the shield tunnel section in detail. According to the monitoring data, the sedimentation tank width coefficient of each section was statistically analyzed and calculated. The error between the calculated results of the different settlement tank width factors and the measured results was contrasted. The width of the sedimentation tank suitable for this project was selected Coefficient calculation formula. On this basis, the prediction formula of settlement deformation is put forward, and the calculation results of the calculation formula are compared with the measured data. The results show that the measured values and the calculated values of the monitoring points of all the sections agree well with each other.
