摘　　要：随着区域性大城市之间城际轨道交通工程快速的发展,铁路路网分布不断完善,新建城际铁路线路下穿既有公路、铁路施工将越来越频繁,如何安全穿越既有线,保证下穿过程既有线行车安全,将是隧道施工的重点、难点。暗挖隧道下穿既有线施工除自身存在高风险之外,如何控制既有线行车的安全性亦是施工控制的重中之重,相关施工工艺及控制措施将会在今后同类施工中得到广泛的应用。结合珠三角城际轨道交通工程东莞至惠州城际铁路下穿广深准高速铁路施工实例,将相关工程技术总结整理,供类似工程参考。With the rapid development of inter-city rail transit project between regional big city,railway network distribution of continuous improvement,through the existing highway,railway construction will become more and more frequent the new intercity railway line,how to safely cross the existing,ensure the wear process of the traffic safety,will be the focus,difficulty in tunnel construction.Tunnel beneath the existing construction in addition to its high risk,how to control the traffic safety is also a priority among priorities in the construction control,will the relevant construction technology and control measures have been widely used in the future similar construction.Combined with The Pearl River Delta inter-city rail transit project from Dongguan to Huizhou inter-city railway crossing from Guangzhou to Shenzhen quasi high speed railway construction case,the related engineering are summarized,for the reference of similar projects.
