Abstract
If lacking scientific and rational planning and management when underground engineering is developed karst collapse risk area, it will bring immeasurable losses to subway construction, operation and disaster relief. To this end, this paper puts forward the concept of “Safety Warning Distance”. According to the final collapse form of karst soil cave-funnel-shaped collapse influence area, the critical slope angle β is proposed in the subway tunnels risk section “Red Line of Safety Warning”. Then the critical safety warning distance safe asafe is calculated by FLAC 3D numerical simulation of the boundary scale of karst soil cave when it finally collapses. This research method can provide a safe and reliable scientific reference for future subway Line adjustment, construction, operation and disaster relief.
