The Application of Piezocone Penetration Test (CPTU) in Water Area Hydrogeological Investigation

Piezocone penetration test device imported from the Netherlands was used to conduct pore pressure dissipation tests at 4 measuring points in 2 holes water area of Sutong GIL utility tunnel project. After dissipation, stable analyse groundwater and further obtain height head. This method provides a successful solution for in-situ stratification testing parameters engineering, reliable hydrologic such as structure design construction
