摘要
以济南地铁R2线彭家庄站至济钢新村站区间大角度近距穿越高速为例,研究了在复杂地层条件下盾构对高速路基沉降变形的影响,采取不同阶段的保护对策及技术方案,对盾构下穿设计与施工进行了指导。综合运用理论分析、数值计算及监测相结合,有效解决了下穿段地层沉降控制技术难题,可为类似工程提供借鉴参考。
Based on the project of large angle short-distance crossing expressway between Pengjiazhuang station and JigangXincun station of Jinan Metro Line R2,this paper studies the influence of shield on the settlement and deformation of high-speed subgrade under complex stratum conditions.Protection countermeasures and technical schemesare adopted at different stages to guide the design and construction of shield structure.Through the comprehensive theoretical analysis,numerical calculation and monitoring,the technical problems of strata settlement control in the undercrossing section are effectively solved,which can provide reference for similar projects.
