Regulation And Prevention And Cure Methods To Groundwater In Mountain Tunnel

With the covariance analysis of groundwater and geology in the mountain range tunnel, induce the factor that influence the tunnel flow outs water. With the investigation of rock separated from the water, The pressed water layer, stress field , the influence to construct ion , inner structure of rock, landform, physiognomy, surface water, climate, and so on. Proceeding the research of the regulation of groundwater, The relation between Iithology and groundwater, geology structure [the character of groundwater in faultage, the configuration character analysis of abundant water in zone of fracture], the influence of cl ime, physiognomy, etc. By the research of interactions between groundwater and rock or soil masses [Physics, chemistry, mechanics function] , Geological hazards and failures induced by groundwater-rock interaction such as subsidence, groundwater flow, it affects the stabiIity of wal I rock , the schedule and safety of construction. Making the detai led craft research of TSP geology forecast and infrared detect water in advance by engineering case that the geology forecast is extra effective before the water flow out of the mountain tunnel.According to the law of underwater in the tunnel and the must needs of environment reserve, together with current construction technology level, that prevention and cure method to groundwater in mountain tunnel should obey the tenet : ' jam is the first, let the water out suitably, colligate the method of prevention> letting^ intercepting and jam to father' . Adopt the main measure of deep hole purdah grouting to prevent underwater, it is emphasizing the construction self watertightness, at the same time the the clear and definite solution measure and method is bring forward to the calculation while design concrete wall resisting water pressure and the craft of construction.
