摘要
总结了地铁隧道盾构施工的施工方法和工作原理,讨论了盾构掘进面支护力产生原因和控制方法。阐述了盾构掘进过程中,围岩的三种压力状态:主动围岩压力状态、被动围岩压力状态和平衡围岩压力状态,得到了支护压力与三种围岩压力状态的关系所对应的地表形貌。
The construction method and working principle of subway tunnel shield construction are summarized. The causes and control methods of the supporting force of the shield tunnel heading face are also discussed. Three pressure states of the surrounding rock which contained active surrounding rock pressure state,passive surrounding rock pressure state and balance surrounding rock pressure state are expounded during the shield driving process. The relationship between the supporting force and three pressure states of the surrounding rock and the corresponding surface morphology are obtained.
