摘　　要：通过对电力隧道盾构施工过程中水土压力监测数据的整理,分析了盾构施工过程中引起的水土压力变化的各种因素,并结合由水土压力变化引起的土体固结所产生的地表沉降值,分析了水土压力变化与地表沉降的关系,得出了一些有益结论,以期对类似的工程实践有所参考。Through analysis of the monitoring data of water and earth pressure of electricity tunnel during the construction, all the factors causing the water and earth pressure change during the construction were analyzed, in combination with the changes of water and earth pressure causing the change of consolidation of soil, and the relation- ship between the surface settlement and water and earth pressure changes, some useful conclusions were obtained, to serve as reference to similar engineering practice.
