Abstract


Our country is a mountainous country, complex terrain, combined with new tectonic movement, fault structure development, seismic activity, making China become the world's most serious disasters slopes one of the countries in the mountainous city expressway construction and maintenance, part of the trunk Since the slope and valley topography conditions, and in the rain, earthquakes and other natural conditions the interaction of a combination of factors, will face a mountain road engineering disasters sudden problems. 2008 of the \The traffic flow is restored after the earthquake relief and reconstruction basis, so research including mountain city expressway emergency disaster prevention and rapid reopened key technology for sustaining economic development, safeguarding people's lives and property safety has important theoretical and practical significance Engineering . Mountain City Expressway sudden disasters is a quick grab ICT complicated systems engineering, the paper first natural conditions on the main road and geological conditions were investigated, based on the completion of the investigation has been built on the main road Lot unfavorable geological risk assessment and in accordance with appropriate engineering evaluation results proposed disposal technology programs; appear on the main road after the disaster off the road bridges, tunnels and other unexpected disasters burial cave reopened programs and reopened measures were analyzed; while the device was provisionally adopted Preliminary studies and reopened equipment were discussed. Studies have shown that mountain city expressway disasters has its time and spatial distribution. Disasters with disaster is high, affecting a wide range, triggering engineering disasters, human activities and other characteristics. According prevention, combining prevention with control, according to local conditions and integrated governance principles, targeted, systematic geological work, control irrational human activities. In reference to previous literature, based on the proposed targeted landslides, mudslides, landslides and other disasters, rockfall prevention principles and techniques. Shinozuka drawing on methods based on the use of parameter correction model of the bridge disaster capacity were evaluated for alternative bridge emergency repair materials were summarized; tunnel sudden disasters rapid evaluation and assessment; according to different evaluation The results presented tunnel reopened sudden disaster programs and measures. In future work should be strengthened through the device of temporary fast and adapt to the rapid development of equipment reopened.
