Research On Highway Tunnel Construction Unfavorable Geological Disaster Treatment Measure System

With China's large-scale domestic infrastructure construction and the implementation of the western development strategy, road tunnel construction has entered a peak period. As the complexity of engineering geology, the geological condition can't be accurately predicted.During the tunnel construction process, we often encounter rock-burst, landslides, water gushing and other unfavorable geological disasters, the project accident triggered by these, ranging from slow progress of the project to increase the project cost, damage machinery and equipment, will result in heavy casualties and failure of the whole project.This article researches the common unfavorable geological disasters during construction process, firstly, search relevant literature about unfavorable geological disasters and find out the basic theory, forecasting methods, treatment measures of the rock-burst, fault, rock disolve, landslides, water gushing, unsymmetrical pressure, etc. Combined with experiences in the Treatment of geological disasters in construction, develops a series of flow chart of treatment for common geological disasters.Secondly, manage treatment by Access2007 database system, at last, develop highway tunnel construction unfavorable geological disaster treatment system based on ASP technology. The system includes four parts:unfavorable geological, geological disasters, special geotechnical, project examples, probably covers geological problems encountered in the construction, conveniently provides treatment measure to geological problems. The system is successfully applied in Changcheng Mountain tunnel's water gushing, and achieved good results.
