摘要
以徐州轨道交通某座集明、暗、盖挖为一体的大型换乘车站为工程背景,分析了进站左右线隧道联络通道上方地层突降水对其邻近隧道衬砌的影响。通过理论计算和数值模拟等方法获得隧道联络通道衬砌沉降规律,并分析了围岩应力-应变状态。计算结果表明,地层突降水会使其附近的隧道衬砌产生明显沉降,获得最大沉降发生位置。基于初衬计算结果对原始方案进行了优化,提出了针对性控制措施。
Based on the research background of the first domestic large-scale transfer station integrating open-cut,subsurface excavation,cover and cut of an Xuzhou rail transit line,the effect of the stratum sudden precipitation of the tunnel’s left and right line of the station on the the adjacent tunnel lining was analyzed.Through established theoretical calculations,numerical simulations and other methods,the settlement law of the lining of the tunnel connecting aisle is obtained,and the stress-strain state of the surrounding rock is analyzed.The calculation results show that the stratum sudden precipitation will cause obvious settlement of the tunnel lining nearby and obtain the maximum settlement location.Based on the calculation results of primary lining,the original scheme is optimized,and targeted control measures were proposed.
