摘要
The paper, by combining the differences and characteristics of rapid and slow water recharge in karst area and from the hydrogeological mechanism and characteristics of karst water movement, used three methods, i.e., water balance method, groundwater runoff modulus method and Expert’s Judging System to predict and analyze karst water bursting in Jinkuidi extra-long tunnel. The water volume calculated by water balance method was the biggest, that by runoff modulus was the smallest, and that by the expert system was medium. Multual verification proved that the expert judging system was the most precise, the method emphasizes the effect of precipitation on karst water bursting in tunnel and increases the precision of karst water inflow prediction in tunnel.
