Study on Forecasting for Water-gushed Yeild of Tunnel

It is discussed that the water-gushed yeild of a tunnel is predicted by utilizing the underground hydrodynamic method and the fuzzy mathematic method. If the parameter date of the hydrology and engineering geology before construction and in initial period of construction are given, the empirical formula in the underground hydrodynamics may be used to forecast the water-gushed yeild of a tunnel as well as its change process. The method may be used to instruct the general design and construction. According to the primary factors to affect the water-gushed yeild of a tunnel, the theory is proposed to forecast the water-gushed yeild of a tunnel by using the fuzzy closeness degree. According to the computed results, it is proved that the forecasted result with the method has a certain reference value.
