Study On Advanced Detection And Disposal Methods Of Yunwushan Karst Tunnel

With the development of infrastructure construction in our country, more and moretunnels build in karst region. Karst region due to the complicated geological conditions,construction of the tunnel is a difficult technical problem both at home and abroad.This articleis on the basis of summarizing the status of karst tunnel construction in the domestie andinternational, combine the concrete conditions of the Yunwushan tunnel, rearchs the advanceddetection and disposal methods technology in karst area.Through the research of karst tunnel cave detection technology, it could determine theboundary, scope, the success of water, water pressure, water quality parameters of the karstcave.Based on the observation of rainfall and inflow of the karst cave, the water balancemethod is used to predict the inflow in most unfavorable conditions, to provide a scientificbasis for making the cavity treatment scheme to reduce the risk of construction.By studyingthe high pressure and rich water, filling cavity rig drilling efficiency get breakthrough,analysising rig parameters ang performance, aimed at different types of cavity filled withdifferent types of form a complete set of machinery, by observation of the change ofsurrounding rock in the process of the detection, and the analysis of the drilling parameterssuch as Angle, length, the more accurate interpretation of the karst cave ahead geologicalfeatures.Researching the energy release and depressurization construction technology, Basedon the analysis of the geological characteristics of the nature of the cavity filler, surface hydrology and cave connectivity to take blasting directly revealed in Cave caverns, so as to reducewater pressure and exclude the risk of the sudden mud water inrush.The technique can quickly fill caverns through the high-pressure, water-rich. Through classifyjing the karst cave, the Yunwushan tunnel has proposed the classification management policy, to form thecorresponding integrated treatment mode and technology solutions systematacially.By using synthesize advanced detection and disposal methods technology in theYunwushan tunnel construction, pasts the karst area safely.the research result of this text canbe provided as reference to the tunnel construction of karst aera.
