摘要
为研究盾构隧道下穿对铁路站场的影响,以长株潭城际轨道交通下穿湘潭北站站场为工程背景,利用有限元分析对盾构隧道穿越施工作风险评估.结果表明结构变形结果和地层沉降均控制在合理范围之内,因此盾构下穿不影响铁路站场的正常运行,评估结果和变形规律总结对同类工程风险控制具有重要参考意义.
Taking Xiangtan North Station of Changzhutan intercity rail transit underrunning as the case,finite element analysis is used to evaluate the risk of shield tunnel underrunning construction to study the impact of shield tunnel underrunning on railway yard.The results show that the structural deformation results and stratum settlement are controlled within a reasonable range,therefore the shield penetration does not affect the normal operation of railway yards.The evaluation results and the summary of deformation rules have important reference significance for the risk control of similar projects.
