摘要
Abstract
The water inrush is one of the main geologic hazards in the construction of deep-buried long tunnel, especially in karst region. Therefore, it is of great importanct to forecast and analyze the quantity of water inrush. Taking a water diversion project in central Yunnan Province for example, the three dimensional mathematical model of seepage flow was established based on the groundwater model software GMS by consideration of aquiferous medium, the hydrogeological structure of rock mass, the characteristics of groundwater flow system and the chemistry of groundwater of tunnel. Compared with the results of traditional cal-culation method and emprical formula, the calculation result differences are analyzed and the feasibility of the numerical computa-tion method was proved. By the model, we make a further systematic prediction of the water inrush quantity in different periods of construction, as well as make an in-depth analysis of construction impacts on surrounding groundwater.关键词
