摘    要:复杂环境条件下大型泥水盾构施工诱发的地表变位的预测与控制是亟待深入研究的重要课题。结合上海长江隧道超大型泥水盾构推进工程,对其上行线隧道穿越民房段前试验段的地表沉降监测数据进行了分析,并采用随机介质理论预测了2条隧道单独及共同施工引起的横向地表变形和位移,据以制定了民房段施工地表变位控制措施。实例分析证明,预测方法和控制措施具有科学性、有效性,有一定的实用价值。

关 键 词:大型泥水盾构  地表变位  随机介质  民房

Abstract:The prediction and control of ground deformation and displacement resulted from large slurry shield tunneling in complicated environment are important problems to be solved. Combined with Shanghai Yangtze River Tunnel Project, the ground settlement data of test section approach to building areas in uplink tunneling is analyzed. The ground surface movement of test section induced by single tunnel excavation as well as cumulative movement due to two parallel tunnel excavation is accurately predicted by using stochastic medium theory. Based on ground movement prediction, recommended procedures for tunneling in a building areas are presented. The case study shows that the prediction method and measures presented for ground movement control are reasonable and reliable and have some practical value.
Keywords:large slurry shield  ground deformation and displacement  stochastic medium theory  building
