| 摘 要： | 给出了采用随机介质理论计算隧道施工引起地表位移和变形的公式及相应参数反分析方法.结合上海长江隧道超大型泥水盾构推进工程,采用随机介质理论对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计算分析.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,评估隧道施工对周围环境的影响程度及分析了地表变位主要影响因素,据以合理地制定了民房段施工地表变位控制措施(包括泥水压力、同步浆量和推进速度).通过实例分析证明了预测方法和控制措施的科学性和有效性,具有一定的实用价值.

| Abstract: | The analytical formulation for ground movement due to tunneling on the basis of stochastic medium theory and relevant back-analysis method are presented.Combined with Shanghai Yangtze river tunnel project,the ground surface movement of test section approach to building areas induced by single tunnel excavation as well as cumulative movement due to two parallel tunnels excavation were accurately predicted using stochastic medium theory.Based on ground movement prediction and evaluation of its influence on su... |
