Piezocone penetration tests with dissipation phases are particularly useful for geotechnical site characterization. They also provide three independent readings with depth from a single sounding as well as time-rate information. In past investigations, only silty sands with specific silt content have been tested and complete sets of tests have not been conducted to evaluate the influence of dif...

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...

In this work the possibility of identifying two important aspects in process adopting soil parameters for calculating stability analysis models tailing dams is discussed. The use commercial computer programs calculations allows obtaining numerically exact results. Its representativeness, however, will be linked to correct definition phreatic regime and prediction volumetric behavior during shea...
