Study on Prediction and Treatment Technology of Karst Fissure Water of Qiyue Mountain Tunnel

LIN Chuan-nian1,2,3(1.School of Civil Engineering and Architecture,Beijing Jiaotong University,Beijing 100044,P.R.China;2.Construction Headquarters of West Section of Hu-Rong Expressway,Enshi,Hubei 445000,P.R.China;3.China Railway 12 Bureau Group Co.,Ltd.Taiyuan 030024,P.R.China)  
Geological disaster forecast and management of karst tunnels is the important technical support to safe and fast constructions.Based on the engineering background of Qiyue Mountain Tunnel in the west section of Hu-Rong Highway,through the geological survey and analysis,researches are done on the karst development law of the tunnel site.Using Tunnel Seismic Prediction method,detection is done on a high karst risk area of YK329+285~YK329+237,and in front of the tunnel face,development areas of karst and underground water are essentially detected.Scientific basis of timely treatment plans are provided.According to the situation of fissure gushing water,after excavation,based on accurately detecting of karst fissures,adopting composite grouting technology,karst water is blocked by grouting.
