Abstract：Numerous tunnels are adopted in railway and highway in western mountainous areas，China. The external water pressure and flow are the most important problems faced in the tunnel construction. In order to calculate the high external water pressure，the rock seepage field and external water pressure coefficient should be treated in detail. External water pressure can be calculated independently or together with confining pressure. The basic theory and method calculating external water pressure are discussed with an example.
