摘要：
The deformation of excavating tunnel of diameter line subway between Beijing Railway Station and Beijing West Railway Station induced by existing subway vibration load is studied by using commercial finite difference numerical simulation software of FLAC. According to the geological exploration data, a typical section of rectangular double-wall drift method is selected to build computing model. According to the calculating results, the deformation rule of excavating tunnel induced by the existing subway vibration load and the underground excavation is analyzed, which provides data supporting and references to specific technology improvement for subsequent construction.
