| Tunnel engineering is now one of the most important construcion prejects and research projects in the world and verious problems may come out in the construction process.Nowadays engineering has begun to pay much attention to the problems of water gushing which can bring serious impact to the construction and design of the tunnels,so the prediction of water flow into tunnel becomes a very important link in the construction of the tunnel.This article study on the prediction of water flow into huama tunnel and research the influence factors of tunnel water inflow in many aspects:(1)research the geological conditions in the huama tunnel area and analyze the geology of the tunnel.A detailed geological conditons investigation has ben set to huama tunnel for the geological structure such as lithology, fault、 flod and so on in huama tunnel is complicated.(2)investigate and discribe the water flow into huama tunnel in different regions and test the water quality in the tunnel.summarize the situations of water flow into huama tunnel and water chemical compositon. estimate the water flow and water presure in huama tunnel.(3)add geophysical prospecting forescast、supplementary geological investigation、 water inrush and so on in the regions which has watering gushing in huama tunnel. add detailed investigation on the source goundwater recharge.Anlyze the situation of goundwater and the reason of water gushing in huama tunnel.(4)anlyze the hydrogeology of huama tunnel, set up the fracture network of rock mass model,reasch the effects of the water inflow of huama tunnel by the anlysis of the fracture network of rock mass model.(5)predict the water inflow of huama tunnel due to different part.build the fracture network of rock mass model in each part of the tunnel and predict the water inflow respectively.Compare the water flow into huama tunnel with the method of empirical formula and numerical simulation and research coulping between stress field and seepage field. |
