| 摘 要： | 在总结地铁盾构施工的控制原则以及盾构通过临近群桩的动态预测方法的基础上，结合武汉地铁的设计，采用数值模拟方法对地铁盾构穿越汉口火车站区时地面及建筑物桩群进行模拟，分析了盾构穿越一般底层和穿越群桩基础两种不同的情况的位移情况，从而对盾构隧道对城市地面以及建筑物的影响做出评价，提供了盾构穿越建筑物施工安全控制的建议。

| Abstract: | Based on controlling principle of metro construction and dynamic forecasting method of group pile-approached by shield tunneling, numerical simulation is adopted to simulate ground and structure group piles approached by shield tunneling of Hankou Railway Station according to design of Wuhan metro and two different displacement cases between no-loading ground and structure group piles approached by shield tunneling are analyzed. Finally, the impact of shield tunnel on city floor and construction could be derived to evaluate; and some helpful suggestions on construction safety control of shield tunneling approaching are offered. |
