In-Situ Testing Technology and Its Application for External Water Pressure in Deep-Buried Tunnels Based on Directional Drilling

[Objective] External water pressure is a critical parameter in the construction design of deep-buried tunnels. During the early investigation stage, it is difficult to obtain this parameter through traditional vertical borehole exploration. In engineering practice, the reduction coefficient method i...
