Abstract:

Taking the construction of the underground running tunnel from Huashi Station~Gangding Station located in soft and fractured ground as example, the paper presents the mining construction technology for the running tunnel underneath busy roads and pile foundations of buildings and probes into the control of the ground surface settlement and blasting vibration velocity for underground running tunnels under special conditions.

Key words: Metro, tunnel, mining method, soft fractured ground, tunnel construction underneath buildings, construction technology, ground surface settlement, blasting vibration velocity
