| Our country highway safety have always been threatened by geological disasters such as collapse, landslides, debris flows and ground subsidence which reduce the driving and driving comfort, lead to traffic blocked and even highway traffic interruption, and cause property losses and casualties. These are very bad impact to economic development along the road, the stability of the society and the consolidation of the border. Scientific and effective rapid repair after a geological disaster is the guarantee of the highway emergency transportation and rescue, the key to cut loss and the powerful safeguard to promote social harmonious Development.Quick-reaction system and emergency command system should response quickly and make decision after the highway geological disasters, and then command the forces repairing the damaged road according to the emergency disposal measures of damaged road.Highway facilities damaged by geological disaster including roadbed, road surface, bridge and tunnel. The destruction of roadbed and road surface can be divided into roadbed subsidence, roadbed collapse, road buried blocked and so on. The destruction of bridge are bridge damage and collapse. The destruction of tunnel cover tunnel hole collapse and the hole blocked, tunnel large deformation and gushing water mud.The article summarizes a emergency disposal theoretical system of highway geological disaster aim at all kinds of damaged highway facilities which is blanket and basic complete. In order to realize rapid repair and service rescue, it is the guide book to rescue the lifeline in practical engineering. |
