摘　　要：当前,空间交叉隧道越来越普遍,由于存在空间距离、建设时序和地质地形等诸多不确定因素,需考虑通过减小扰动、提高支护参数及加强监测等措施来确保两隧道结构安全。该文以沿山货运通道(新图大道)核心区一期工程(Ⅱ标段)为例,介绍了该隧道交叉段的相关加强设计,并通过数值模拟计算两隧道间的相互影响,可为今后类似工程的设计工作提供借鉴。With the increasing prevalence of spatially intersecting tunnels,uncertainties such as spatial distance,construction sequence,and geological terrain must be managed to ensure structural safety through measures like minimizing disturbances,enhancing support parameters,and strengthening monitoring.This paper uses the firststage project(Section II)in the core area of the Along-Mountain Freight Transport Channel(Xintu Avenue)as a case study to discuss the reinforcement design of the intersecting section of tunnels.Numerical simulation is employed to calculate the mutual effects between the two tunnels,providing insights for the design of similar projects in the future.
