ANALYSIS ON SLIDE MECHANISM DURING CONSTRUCTION OF TUNNELS AND ITS TREATMENT METHODS
ZHENG Yu-xin (Tunnel Engineering Bureau of MOR)
During the excavation of tunnels, the slide often occurred. The paper analyzes the main causes of the occurred slides and the slide mechanism. The patterns of the slides are concluded as 5 kinds, including 16 different types. The treatment methods are also proposed, which consist of two classes,i. e,the treatment of slide inside of the tunnel and the treatment of slide at the entrance of the tunnel. According to different situations,the treatment methods are expounded in detail. These meth ods may be applied for reference.
