Calculation Methods for Water Inflow from Typical Sections in a Long Deep Buried Tunnel

Abstract:

This paper focused on five kinds of methods for water inflow of typical sections in a long deep buried tunnel under conditions of high ground stress and high water pressure (referred to as “two high conditions”). The methods are based on groundwater dynamics formulae and practical experience. Results show that calculation data by the method 5 is the maximum. There is little difference of calculation results between the formulae 1 and 2 or between the formulae 3 and 5. The calculation methods and results of the water inflow can provide prevention of gushing water of a long deep buried tunnel under the two high conditions with scientific basis.
