Abstract In hydrogeology survey of railway engineering，the method using isotopic tritum (3H) to understand the formed ages and supply characteristics of underground water,and to predict the permanent discharge of tunnel and supply amount of water resource,was testified available in local engineering. The isotopic tritium(3H)method is a new technics In spite of its complex theory,the method is thotlght to be simple and the result has a higher believable degree. Operation in site’analysis and its calculation method for local engineering are intro?duced in this paper.
