摘要
文章以东珠三角城际轨道交通广佛线东环隧道工程为工程研究背景,运用数值模拟和理论分析相结合的方法,分析了东环隧道工程对货车外绕线太和隧道结构的影响。通过分析盾构掘进、支护施作对铁路隧道结构安全性产生的影响,得出结论交叠隧道施工过程中交叠段存在相互影响,表现为既有隧道交叉段的漏斗段沉降。文章的研究对后续研究交叠隧道的施工有一定的指导意义。
Taking the East Ring tunnel project of Guangzhou-Foshan Line of intercity rail transit in the East Pearl River Delta as the engineering research background,this paper analyzes the influence of the East Ring tunnel project on the structure of Taihe Tunnel of freight car outer winding by combining the method of numerical simulation and theoretical analysis.By analyzing the influence of shield tunneling and support on the safety of railway tunnel structure,it is concluded that overlapping sections have mutual influence in the construction process of overlapping tunnel,which is manifested as the settlement of funnel section in the cross section of existing tunnels.The study of this paper has a certain guiding significance for the subsequent study of overlapping tunnel construction.
