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