摘要
依托深圳地铁11号线车公庙站～红树湾站盾构区间隧道工程,基于监控量测和数值模拟,就隧道上覆淤泥地层对地表沉降的影响进行分析.分析表明了淤泥地层会显著地增大地表沉降和沉降槽影响范围,并得到了地表沉降随淤泥地层分布深度、分布厚度的变化规律.研究成果可为类似工程提供借鉴.
Based on running tunnel of Shenzhen subway line 11, analysis of the influence of silt layer above shielding tunnel on ground subsection with monitoring and numerical simulation is presented in this paper. Analysis shows that ground subsidence and its influence scope is significantly increased because of silt layer. Besides, the relationship between ground subsidence and depth, thickness of silt layer is achieved. The results can provide reference for similar projects.
