Abstract:
Aiming the water inflow in the advance geological exploration during the construction of the transverse adit of the Xiongdongwan tunnel determined the nature of the water source. Countermeasures were established by means of geographic and geomorphic investigation, TSP advance geological forecasting, infrared detection, advance geological drilling, and water quality inspecting. This paper introduces the background and geological characteristics of this project and analyzes the causes of water inflow and the countermeasures that may be used to address them.
