摘要: 地铁深基坑的周边保护环境要求很高，加之各个地区的工程水文地质条件不同，研究并制定适合于当地情况的监测监控指标值非常重要。在对地铁深基坑监测监控指标的涵义进行探讨的基础上，提出地铁深基坑监测监控指标的研究思路，并结合宁波地区1号线12个基坑140个测斜孔的监测数据，对基坑测斜分层控制指标进行了研究，并得到一套分层控制指标值，具有一定的参考价值。Abstract: Because of the high requirements for protecting the surroundings around deep excavations of metro (DEM), it is important to study and establish the monitoring index system for DEM. Moreover, as a result of hydrologic and geologic conditions varying from one territory to another, it is necessary to establish the monitoring index system which is suitable for local situation. Based on discussing the connotation of the monitoring index system for DEM, the ideas for the monitoring index system for DEM are described. Monitoring data of 140 inclinometer holes in 12 excavations of Ningbo Metro Line One are integrated to study the hierarchical control indices of DEM. And a relevant control index system, which is valuable for reference, is obtained.
