Study on Key Technology of Deep Excavation Construction in Metro Transfer Station

Engineering of city underground traffic construction is affected by many uncertain factors,which include complicated hydrography and geologic conditions,dense traffic flux on the ground,anfractuous city planning underground,multi-vary resultant structures,difference construction methods,obligates on difference underground lines,etc.For the dependability of the construction,all kinds of technique difficulties and emphases must be analyzed particularly in depth,and effective and pertinent technique measures must be established,coordinated with management system in order to reduce the construction risk in the underground engineering and insure the large exchange station been putted in practice according to the anticipation.
