Gushing Water of a Deep Buried Long Tunnel under High Water Pressure and High Ground Stress

Abstract:

This paper focused on calculation of gushing water and evaluation of calculation methods. A groundwater runoff modulus method, a rainfall infiltration coefficient method and a groundwater dynamics method were used to calculate volume rate of water inflow of an ultra deep buried long tunnel under conditions of high water pressure and high ground stress (referred to as two high conditions). Results show that the more volume rate of water inflow occurs in a fault zone with fault gouge, a karst stratum zone and their combination zone. The calculation results by using modified Goodman formula have the highest precision. The results can provide prevention of gushing water of a deep buried long tunnel under the two high conditions with scientific basis.
