摘要：

This paper focused on groundwater flow in certain a tunnel site under conditions of high ground stress and high water pressure (referred to as "two high conditions"). Three-dimensional conceptual model was established for groundwater flow in porous strata with argillation weak permeable media in a long deep buried tunnel site. Groundwater flow field was studied by means of three-dimensional numerical simulation. Results show that there is good agreement between numerical simulated and observed groundwater table and that the conceptual model and the numerical simulation are reliable. Prevention measures should be adopted for a long deep buried tunnel construction. The results can provide evaluation of engineering safety of a long deep buried tunnel construction with scientific basis.
