摘要
用收敛仪和精密水准仪直接量测监测盾构隧道的成型环片的收敛和拱顶下沉情况;监测盾构掘进过程引起的地表变形情况。根据监测结果进行分析,判断盾构掘进对地表沉降的影响。对比实测数值与初始数值,绘制地面隆降时态曲线,运用回归分析法进行分析并及时反馈,以调整施工参数。
The situation of shaped ring piece convergence and vault subsidence in a shield tunnel is monitored directly with a convergence instrument and a precise leveling instrument and the earth surface deformation by the shield-driven processing is monitored too.According to the monitoring result,we can do some analysis and judge the influence which shield driven processing effects on the earth surface subsidence.Comparing the real measured value with the initial measured value,the temporal curve on the earth surf...
