| 摘 要： | 按照盾构施工引起的地层扰动机理及变形特点,将盾构施工对周围地层的扰动过程分为5个阶段,即:盾构机到达之前土仓压力影响阶段、盾构机通过阶段、管片衬砌脱出盾构机盾尾阶段、管片壁后浆液硬化阶段以及扰动土层的蠕变固结阶段,对盾构隧道施工各个阶段的地面沉降、土压力及孔隙水压力的变化过程进行监测,并分析其各自的变化特点。针对盾构施工过程的5个阶段的施工扰动特点,探讨各阶段相应的施工扰动控制要点。 |
| 关 键 词： | 盾构施工 扰动 地层变形 孔隙水压力 土压力 施工控制 |

| Abstract: | According to the disturbance mechanism and characteristics of strata deformation,the disturbance process due to shield tunnel construction can be divided into five stages: stage of chamber earth pressure influence,stage of shield machine passing,stage of tunnel segments being pulled out from shield tail,stage of grout hardening behind segment and stage of creeping and consolidating of disturbed strata.The variation processes of pore water pressure,ground deformation and earth pressure above the shield tunne... |
| Keywords: | shield tunnel construction disturbance stratum deformation pore water pressure earth pressure construction controls |
