摘　　要：随着电力电缆隧道直径逐渐加大、埋深逐渐加深,在施工过程中会对地表周边环境造成较大的影响。本文利用盾构法隧道施工技术对环境影响小且施工快的优点,结合对上海世博北京西路～华夏西路电力电缆隧道工程监测的数据,并考虑盾构施工的相关因素,采用土体扰动机理,得出了盾构隧道施工过程中地表纵向及横向断面沉降的规律。同时,阐述了如何合理使用peck曲线对横向沉降进行预测,控制施工中地表的沉降。With the gradually increasement of diameter and depth of the power cable tunnels, tunnel construction will course more influence on environment. Based on advantage of the small environmental impact and quick construction, in this paper, using the monitoring data of Beijing West Road - Huaxia West Road Power Cable Tunnel of Shanghai Expo and considering relative factor of construction, the traverse and longitudinal displacement regularity were got by the mechanism of soil disturb. In the meantime, how to use peck curve to predict the traverse displacement so that controlling the ground displacement in construct period was also presented.
