Beschreibung
Zusammenfassung:	The invention discloses a method and a device for assessing risks of close-spaced tunnels on a high-speed railway roadbed. The method includes determining loosening areas and disturbed areas of the close-spaced tunnels to be excavated; determining all stages of bearing areas of the high-speed railway roadbed according to additional pressure generated by ground load at the position where the high-speed railway roadbed is located and gravity stress of the soil layer; and assessing the level of engineering risks of the close-spaced tunnels on the high-speed railway roadbed according to the calculated overlapping degree of the loosening areas of the close-spaced tunnels and all stages of bearing areas of the high-speed railway roadbed and the calculated overlapping degree of the disturbed areas of the close-spaced tunnels and all stages of bearing areas of the high-speed railway roadbed. The method and the device establish the level of engineering risks of the close-spaced tunnels on the high-speed railway roadbe
