摘要
为确认香炉山隧洞7号支洞施工中是否对大丽铁路花兰箐隧道交叉段结构及安全运行造成影响,论述了二者基本情况、相对位置关系及工程地质条件,并采用相关规范进行理论计算的基础上,进一步采用MIDAS-GTS-NX有限元软件对施工过程进行数值模拟,理论及数值仿真分析结果均表明既有铁路隧道在7号支洞施工过程中的各项的指标均在规范允许范围内,大丽铁路花兰箐隧道结构处于安全状态。
In order to confirm whether the construction of No.7 branch tunnel of Xianglushan tunnel will have an impact on the structure and safe operation of hualanqing tunnel crossing section of Dali Railway,this paper discusses the basic situation,relative position relationship and engineering geological conditions of the two,and further uses midas-gts-nx finite element software to simulate the construction process on the basis of theoretical calculation by using relevant specifications.The theoretical and numerical simulation results show that the indicators of the existing railway tunnel during the construction of No.7 branch tunnel are within the allowable range of the specifications,and the hualanqing tunnel structure of Dali Railway is in a safe state.
