Abstract Based on the analysis on the theory of numerical methods for calculating the amount of water flow ing into the tunnel， the complicated hydrology problem is dismembered and turned into some sorts of typical problem to be solved，and the computer flowsheet is drawn up. Meanwhile，according to the study on Xianrencha fault in Qinling extra~long tunnel of Xi 'an—Ankang railway， the maths model is established and the amount of water flow has been calculated. The good results are obtained compared with the real water flow volume.
